RR and BGP group

Dear Sirs

 

I have trouble understanding the cluster concept.

below is my bgp group

 

root@vMX2> show bgp group
Group Type: Internal AS: 1111 Local AS: 1111
Name: IBGP-STD Index: 0 Flags: <>
Holdtime: 0
Total peers: 3 Established: 3
11.11.11.11+63591
44.44.44.44+179
33.33.33.33+51429
Trace options: detail recv update
Trace file: /var/log/bgp_ror size 131072 files 10
inet.0: 5/6/5/0

 

Group Type: Internal AS: 1111 Local AS: 1111
Name: IBGP-RR Index: 1 Flags: <>

Holdtime: 0
Total peers: 2 Established: 2
88.88.88.88+179
66.66.66.66+63537
Trace options: detail recv update
Trace file: /var/log/bgp_ror size 131072 files 10
inet.0: 0/5/3/0

Groups: 2 Peers: 5 External: 0 Internal: 5 Down peers: 0 Flaps: 25

inet.0

base on my existing understanding, group IBGP-RR bgp neighbor will be the route-reflector client. as such, the rule where the route i receive from the group IBGP-RR will be reflected with each other as below :

 

root@vMX2> show route receive-protocol bgp 88.88.88.88

inet.0: 33 destinations, 38 routes (32 active, 0 holddown, 3 hidden)
Prefix Nexthop MED Lclpref AS path
99.99.99.0/24 88.88.88.88 0 100 I
100.100.100.0/24 88.88.88.88 0 100 I
120.120.120.0/24 88.88.88.88 0 100 I

 

root@vMX2> show route advertising-protocol bgp 66.66.66.66

inet.0: 33 destinations, 38 routes (32 active, 0 holddown, 3 hidden)
Prefix Nexthop MED Lclpref AS path
* 36.255.39.0/24 2.2.2.3 100 I
* 36.255.41.0/24 2.2.2.3 100 I
* 99.99.99.0/24 77.77.77.77 0 100 I
* 100.100.100.0/24 77.77.77.77 0 100 I
* 210.210.210.0/24 49.49.49.9 0 100 9255 I

 

On what i have read so far too, i will also be able to advertise the route i am learning from 88.88.88.88 to the non-clients in group IBGP-RR. however i am not able to do that as below :

 

root@vMX2> show route receive-protocol bgp 88.88.88.88

inet.0: 33 destinations, 38 routes (32 active, 0 holddown, 3 hidden)
Prefix Nexthop MED Lclpref AS path
99.99.99.0/24 88.88.88.88 0 100 I
100.100.100.0/24 88.88.88.88 0 100 I
120.120.120.0/24 88.88.88.88 0 100 I

 

root@vMX2> show route advertising-protocol bgp 11.11.11.11

 

root@vMX2> show route advertising-protocol bgp 33.33.33.33

 

root@vMX2> show route advertising-protocol bgp 44.44.44.44

root@vMX2>

 

per my understanding, the particular router will also not advertise route it receive from 11.11.11.11 and towards 33.33.33.33 as those are non-clients of this particular router, which is on the following behaviour below 

root@vMX2> show route receive-protocol bgp 11.11.11.11

inet.0: 33 destinations, 38 routes (32 active, 0 holddown, 3 hidden)
Prefix Nexthop MED Lclpref AS path
* 36.255.39.0/24 2.2.2.3 100 I
* 36.255.41.0/24 2.2.2.3 100 I

 

root@vMX2> show route advertising-protocol bgp 33.33.33.33

root@vMX2>

 

my question will be is there a configuration error that i am not able to advertise the route i receive from my client to my non client of this particular router ?
