BGP MPLS Route Reflector issue

Ammartehsein
Level 1
Level 1

I am having an issue in the MPLS Route reflector config. The route reflector is not receiving any mp-bgp routes.

RR config:

router bgp 500
no synchronization
bgp router-id 70.70.70.70
bgp log-neighbor-changes
neighbor MPLS peer-group
neighbor MPLS remote-as 500
neighbor MPLS update-source Loopback1
neighbor MPLS route-reflector-client
neighbor 10.10.10.10 peer-group MPLS
neighbor 20.20.20.20 peer-group MPLS
neighbor 30.30.30.30 peer-group MPLS
no auto-summary
!
address-family vpnv4
neighbor MPLS send-community extended
neighbor 10.10.10.10 activate
neighbor 20.20.20.20 activate
neighbor 30.30.30.30 activate

 

BGP table version is 1, main routing table version 1

Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd
10.10.10.10 4 500 53 53 1 0 0 00:43:04 0
20.20.20.20 4 500 52 52 1 0 0 00:43:06 0
30.30.30.30 4 500 54 52 1 0 0 00:42:56 0

 

RR#sh ip bgp vpnv4
RR#sh ip bgp vpnv4 all

PE1 config:

router bgp 500

PE1#sh ip bgp summary

Gateway of last resort is not set

This worked for me

address-family vpnv4
neighbor MPLS send-community extended
neighbor MPLS route-reflector-client

one more step need (additional to what you config)
under
address family vpnv4 unicast 

neighbor x.x.x.x route-reflect-client 

this need in RR of bgp 

MHM

RR(config-router-af)#neighbor 10.10.10.10 route-reflector-client
% Activate the neighbor for the address family first

This is the error 

This neighbor must activate via 

Address family vpnv4 unicast 

Neighbor 10.10.10.10 activate 

The  you can config route-reflect-client via

Neighbor 10.10.10.10 route-reflect-client

MHM

This worked for me

address-family vpnv4
neighbor MPLS send-community extended
neighbor MPLS route-reflector-client

You need to config route reflect under vpnv4 

MHM

Hello,

what if you activate the peer group instead of the individual peers ?

So instead of:

address-family vpnv4
neighbor MPLS send-community extended
neighbor 10.10.10.10 activate
neighbor 20.20.20.20 activate
neighbor 30.30.30.30 activate

try:

address-family vpnv4
neighbor MPLS send-community extended
neighbor MPLS activate
