Selective default route is possible with BGP?


Re: Selective default route is possible with BGP?

With the loss of source routing in forwarding routing instances, the only option I see for this is to move the server subnets desired into their own full virtual router routing instance.

 

This virtual router can the connect to the SRX directly by adding a subinterface and dedicated link on the SRX connection peering bgp to prefer this path. 

 

If the alternate path is wanted as a backup you add a logical tunnel internal itnerface to the main or root vr and peer there with import of routes as a secondardy path.

Is the SRX in packet mode as a router or in the default flow mode as a firewall?

 

If it is in the default state, (firewall flow mode) in addition to the return route you also need to add security policy zone to zone to permit the desired traffic flows.

L3VPN vrf bgp peer local-as, as loop affect whole vrf tables

$

Hi

Below is the L3VPN PE configuration, the MPLS MPBGP ASN is 18181, there is the local-as 9696 setting in vrf AGC.

 

We also have a ASN 9696 in remote site vrf routing-options autonomous-system setting .

 

My question is the local-as setting in vrf AGC that affects this local_PE all vrf tables and all BGP routes with AS path 9696 become AS loop.

 

The L3VPN vrf local-as setting behavior is different from global setting local-as.

 

Please help me in detail to understand this difference.

Dear Francis,

 

thanks for your reply, but actullally Juniper router is the Head-end and Huawei is the tail-end, and we suspect the extra RESV message after the ResvTear message to cause this stuck issue.

 

Thanks

Dears,

 

I tried searching the board but couldn't find anything specific.

 

I would like to know how to configure show-community-both or show-extended-community under a specific neighbor on MX2020 series.

Hello all,

 

I have an issue when I try to test radius server in MX104 ( Junos 17.3 ) . When I exec command test access radius-server 172.28.30.95 user JOHNDOE password JohnPass secret No1Knows , the output is empty . I reach the radius-server IP ok and this same issue happens with any user . Could you help me please? Thanks a lot . BR .

Hello,

"send-community*" is a CSCO-specific knob, there is no JUNOS equivalent.

JUNOS allows You to attach ANY community to a BGP route using just the policy, without extra hoops to jump through.

MX Type5 EVPN routes

$

Trying to get some type5 EVPN routes working in my lab and and running into some issues.

Setup is that I have two vMX devices connected together via L3 links. These act as the "datacenter gateways"

 

The type5 route is being advertised from MX2 to MX1 however traffic does not flow.  The route is received on MX1 into the bgp.evpn table, however, it is not getting into the customer VRF, which I believe is the problem. Here is some details:

 

root@DC2-VTEP1> show route advertising-protocol bgp 192.168.0.1 detail table bgp.evpn.0  <snip>

The route is received on the other MX:

                      Local via irb.330 

So what i would expect to happen is that the "5:192.168.0.9:440::0::10.4.1.0::24/248" type 5 route in the bgp.evpn table someone needs to make it into the VRF_CUST-1 table.

The config on the exporting side is this:

root@DC2-VTEP1> show configuration routing-instances VRF_CUST-4               
instance-type vrf;
interface irb.440;
route-distinguisher 192.168.0.9:440;
vrf-import VRF-IMPORT;
vrf-target target:40:440;
routing-options {
    auto-export;
}
protocols {
    evpn {
        ip-prefix-routes {
            advertise gateway-address;
            gateway-interface irb.440;
            export TYPE-5;
        }
    }

root@DC2-VTEP1> show configuration policy-options policy-statement TYPE-5
term 1 {
from protocol direct;
then {
next-hop self;
accept;
}
}
then reject; }

I believe there is a special BGP extended community that type-5 routes use, however i'm not sure what it is, so on the import side perhaps i'm not allowing it:

root@vtep1> show configuration routing-instances VRF_CUST-1  
instance-type vrf;
interface irb.110;
route-distinguisher 192.168.0.1:110;
vrf-import VRF-IMPORT;
vrf-target target:10:110;
routing-options {
    auto-export;
}

root@vtep1# show policy-options policy-statement VRF-IMPORT 
term IMPORT {
    from community [ COMM-VLAN10 COMM-VLAN20 COMM-VLAN30 COMM-VLAN40 ];
    then accept;
}
then reject;

Hi,

 

This is very old knob. Instead, try the following knob:

 

If its general user:

test aaa authd-lite user test@test.net password test123 profile AAA  

 

For PPP:

test aaa ppp user test@test.net password test123 profile AAA  

 

for DHCP:

 test aaa dhcp user test@test.net password test123 profile AAA  

 

For example:

 

test aaa authd-lite user test@test.net password test123 profile AAA

bit more info... i'm seeing 10.4.1.0/24 as a hidden route DC1-VTEP1

i'm assuming it's not working because there is no route to the "Protocol next hop: 10.4.1.1"

Juniper x86 platform which supports Vmware or MS virtual machine .

Hello Team ,

 

As a partner working on MX modular platforms . Could You verify if Juniper have any OEM x86 platform (server or appliance) that allow them to setup VMware or MS virtual environment? We have to know if Juniper platform supports this kind of server .

 

We would really appreciate your quick response .

 

Thanks in advance !

Juniper does not provide any hypervisor appliances. You have to find the hardware for a virtualization infrastructure elsewhere.

There is a partnership with Nutanix where vSRX has recently been certified for - but not something you can buy from Juniper.

 

In general both VMWare and KVM is supported for all virtual platforms but only HyperV on a very few (with limitations as well).

Hello Jonas, 

 

Thank you so much for your response . 

 

I understand that , but does juniper have any router or appliance which is x86 CPU system based , where we can install vmware on top of that . something related to service containerization/App hosting virtualization on OS feature .

 

But we are looking speciafically to Vmware deployment over Juniper box/applicance . 

 

Appreciate your quick response .

 

Thanks in advance.

There is no Juniper products/platforms where you can run VMware on top. The closest match is the NFX platform where you can deploy a few virtual machines. This is integrated into a Junos management infrastructure and KVM based. You cannot create a "KVM cluster" based on NFX.

 

If you want to explore this path, the NFX250 is the closest match.

Thanks for the reply. It helps...a bit....It appears that I need umpteen plus one explanations...

 

Unless I am misundertanding the article you referred to, or I did not explain the issue clearly, it is not directly connected subnets that I described.....

 

The issue is when traffic flow is THROUGH switch B in the middle destined for a subnet on switch A or C.  Transit traffic at switch B.

 

When traffic transits switch B for a destination on switch A and is sourced by switch C or vice-versa, it seems to fail.

 

I hope that clarifies. If I am still not understanding the article, please feel free to clarify to me.

 

Thanks again.

VRRP issue on MX104 when adding second VRRP

Dear All,

 

we have two MX104 in two VRRP groups
MX-B - master in vlan 151, backup in vlan 994
MX-A - backup in vlan 151, master in vlan 994

 

There is no any problem when only one VRRP in vlan 151

Type escape sequence to abort.

Packet sent with a source address of 10.0.0.60
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/8 ms

The VIP address is reachable for customer's hosts and hosts reachable from outside.

 

Then we adding second VRRP on separate interface the first VRRP in vlan 151 stop working, VIP address don't respond to ping from customer's hosts and hosts are unreachable from outside networks. But ARP record for hosts are still visible on VRRP master after clearing.

..why not try a differnet vrrp group number as both are the same 0

the VRRP mac address is the same if the group number is the same
