Good day. I just want to tap your expertise on this matter. Our current network is being setup with a diagram below. When NYR1 BGP link going to ATT MPLS was DOWN we are not receiving the expected routes (167.1.x.x, 167.2.x.x, 167.3.x.x) to our TX router which is going to our primary link.
Our BGP neighborship with ATT(AS 39152) from TX(AS 39289) is still up at this time.
On the other hand, expected routes (167.1.x.x, 167.2.x.x, 167.3.x.x) are still being received from LA router going to secondary link. We do not have any access from any NY routers as these are being managed by ATT provider.
TX and LA router do not have any connections between them. R1 and R2 India routers are being linked by an EIGRP.
Is there any way that we can failover to our secondary link which is the LA router going to India R2 whenever NY R1 BGP link to ATT is DOWN (167.x.x.x routes are not being received in TX router) ??
We have an issue wherein NY R1 BGP link going to ATT is down, TX not receiving expected routes and the link we are still using is the primary link (going to India R1). Until NY R1 BGP link was resolved our client in NY was down.
Just want to know if there is a possibility to use the secondary link(ATT going to LA going to India R2) once the routes were not received in TX router.
Its not using the secondary link automatically (ATT going to LA going to India R2). As soon as NY R1 BGP link went up, everything went back to normal operation.
I would query the advertisement from India 2 and LA bgp rtrs?
Is india 2 actually sending all it prefixes to LA and if so LA forwarding them on to you.
Do you have any filtering negating the advertisement of these routes?
