Conditional advertisement in eBGP based on ISIS status

Hello networkers,

In MPLS L3VPN, can we advertise a route to eBGP neighbor only if there is at least one ISIS neighbor up ? (ISIS is the IGP and running in GRT). PE is an ASR 9010.

The neighbor is dual-homed and the advertised route from PE to neighbor is a default generated using default-generate.

Thank you

Thank you

To use this, I need to create as many IP SLA objects as ISIS neighbors. each IP SLA will ping a neighbor.

Gonna be hard to maintain as we should update config whenever we add/remove neighbors .. also convergence will be longer ..

Thanks Sam

if rib-has-route would work with a prefix-list containing hosts like RR or NMS which are always up
