BGP not receiving connected routes from peer

General questions
1

Hello Guys,
I have a BGP session between the Vyos (CPE) and a other Vendor device (PE).
The PE is doing a redistribution of connected routes but I am not receiving those routes in BGP on the Vyos (CPE). I did the same peering with a Cisco router and the Cisco receives the routes from the PE but the Vyos refuses the routes (this makes me feel there is nothing wrong with the PE config). Need help to figure out if I am doing something wrong here.

Hi!

Can you provide the output of the following commands?

show version
sudo vtysh -c "show run bgp"
show bgp ipv4 neighbors 10.250.133.38 received-routes

Also if you can share the advertised from the PE to VyOS would be great. Thanks!

Total number of prefixes 180

4

It is a directly connected network
Won’t receive via bgp

5

The underlay is via an IPsec site-to-site VPN which is up and working. Also the BGP comes up and there only seems to be issue with the updates.

6

In PE# output, advertised routes, why is next-hop 0.0.0.0 instead of 10.250.133.38 ?

7

Because these routes are locally originated on the PE as connected and are redistributed in BGP.

8

The PE is doing a redistribute connected in BGP which should propagate the locally connected subnets on the PE towards CPE.

9

Seems like when the PE is announcing more than 150 routes to the Vyos it stops responding or taking in the updates. Strange part is that for existing sessions if I announce more routes it works. I am going to try increasing the memory and CPU.

10

As there is tunneling going on, check for MTU issue. Maybe too much routes doesn’t end up in fragmented packet, but oversized packet instead. Use mss-clamp
