Hello guys
We have two EX4200 installed with virtual chassis and we want to use it as a router with several LACP aggregations, for example:
On the top of our infrastructure we have a router (edge router) that receive the upstream link providers and make the BGP announce. This router will route the announced prefixes to the EX4200.
In the middle of our infrastructure, we want to use the EX4200 as a router (Gateway to our prefixes) with several LACP aggregations(distribution layer). The LACP interface will be forwarded to the LACP interface in a logical interface for the switches access, for example:
Edge Router:
Ae0 -> 10.254.254.1/30
Prefix announced and static routes to EX4200: 172.16.0.0/24 via 10.254.254.2
Ex4200:
Ae0 -> 10.254.254.2/30 (Outgoing Interface)
# Show vlans
LAN {
Vlan-id 10;
Interface {
Ae1;
Ae2;
Ae 3;
Ge-0/0 / 10.0
Ge-1/0 / 10.0
}
# Show interfaces vlan unit 10
Inet family {
Address 172.16.0.1/24;
}
So the idea here is that any interface (LACP and individual interfaces) associated with the vlan (logical interface) named LAN has the IP 172.16.0.1 responding to use it as gateway on the access layer.
I am new to JuniperOS and am confused about how I could do this. I tried to use virtual routing (routing-instances), logical interfaces with VLAN and policies to allow forward traffic, but no success. I can't make the traffic forward.
Any recommendation / example / help would is greatly appreciated.
Thank you
Regards
