iBGP routes are not advertised to neighbor by ISR4451

Chanuka D · ‎08-15-2022

Hi All,

I'm having below setup in my network. ISRs are is acting as route-reflectors. Huawei F1A is a route reflect client. MikroTik 1 and 2 are normal iBGP peers. Huawei F1A is advertising 2 prefixes to route-reflectors via iBGP. However, these two prefixes are not advertised to MikroTik 1 by both RR1 and RR2. The same prefixes are advertised to MikroTik 2 by both reflectors. Below are my findings and troubleshooting did. I could not think of anything else as same ISRs are advertising the prefixes to other routers without any issue. Appreciate your guys input to find out the root cause. I can share any configuration upon request.

1. 2 iBGP routes exist in RR bgp table.
2. Next-hop is reachable
3. Synchronization is disabled.
4.BGP sessions has been re-established

only share the RR config and
show ip bgp in both RR

Hello
can you confirm if the RRs are peer to each other?

Hi Paul,
Yes they are peer to each other and sharing one cluster id.

Now the possible issue using a single cluster-id with dual RR its that a form loop prevention just like as-path
debug bgp ipv4 unicast updates - post the output

Hi,
103.78.33.252 is my loopback of MikroTik 1. It is advertised via IGP not redistributed.

emurray · ‎08-16-2022

Are you peering with the loopback?

Chanuka D · ‎08-16-2022

Yes. all routers use loopback IP for peering.

MHM Cisco World · ‎08-15-2022

no valid path for 93.189.208.0/21 <<- this meaning that Next-hop is unreachable
but you mention that the next-hop reachable ??
I think that the next-hop is learn via BGP and hence you enter into LOOP.

Chanuka D · ‎08-15-2022

YEs. next-hop is 103.78.33.252, it is reachable from both RR. no packet loss

MHM Cisco World · ‎08-16-2022

That not correct to check next hope

Select any bgp prefix, use it next hop in ping ftom mikro

The bgp peer is reachable but prefix next hop is not,

That because we deal with ibgp peer which keep next hop unchanged.

Chanuka D · ‎08-16-2022

Hi the issue is not the prefix next-hop. My own prefixes are not advertised to iBGP neighbor by RR.

MHM Cisco World · ‎08-16-2022

the RR reflection the prefix it receive from RR-client to all other NON client,
here Huawei (RR-client)
the Mikro is NON-Client

RR advertise the prefix BUT before Mikro receive the prefix it valid it...
here the Issue when the RR reflection the prefix it not change the next-hop which is Huawei,
the Mikro must valid the path and the next-hop is Huawei BUT it dont know how reach Huawei so the prefix it refuse by Mikro.

use next-hop-self in RR and issue will be solve
