WB 1 Section 7.8
Hi All,
When i checked routes learned from R2 on SW4 i got below given o/p
Rack1SW4#sh ip bgp 205.90.31.0
BGP routing table entry for 205.90.31.0/24, version 15
Paths: (1 available, best #1, table Default-IP-Routing-Table)
Not advertised to any peer
200 254
155.1.0.2 (metric 2174976) from 155.1.58.5 (150.1.5.5)
Origin incomplete, metric 0, localpref 100, valid, internal, best
My question is why cluster-id is not added in these updates ....i am missing something or this is normal bgp behaviour?
Comments
I would check on R5 to make sure you have SW4 configured as a route-reflector-client.
show ip bgp 150.1.10.10 pol

Cluster-id is not shown if the RR is advertising its directly connected network to ther client or if you have any kind of issue in RR configuration. I think you should check for the RR configuration & make sure that the route is advertised by RR has cluster-id as shown below:
Here is the example.
R3---R1---R2
R1(config-router)#do sh run | sec router bgp
router bgp 100
network 150.1.11.11 mask 255.255.255.255
neighbor 150.1.2.2 remote-as 100
neighbor 150.1.2.2 update-source Loopback0
neighbor 150.1.2.2 route-reflector-client
neighbor 150.1.3.3 remote-as 100
neighbor 150.1.3.3 update-source Loopback0
neighbor 150.1.3.3 route-reflector-client
