Hello group,
I have the following situation, I have 2 BGP routers connected to two ISPs,
and connected to
each other with an IBGP session.
each of these routers has a network behind them (x,y), and each router
learns about the other
routers network VIA IBGP,
please look at the diagram below
ISP router A ISP Router B
| |
| |
| |
EBGP link Ebgp link
| |
| |
| |
Border Router A -----IBGP link--------Border router B
| |
| |
| |
| |
Network x Network Y
| |
| |
Pix A Pix B
| |
| |
| |
------------Network Z------------
Now if I lose the link between border router A and border Router B, router A
can't tell
Router B about network x and vice versa.
both routers advertise x and y, but they prepend the other routers network
when they send it
to the ISP, for example, router A send both x and Y to ISP A but he sends
YYY.
now I want to configure A and B so that if the link
between the routers is lost, and the IBGP route about x, and Y are gone, a
floating static will
kick in to tell router A for example that to get to Network Y go to Pix A.
I'm not having luck with the config, If I put a floating static router with
admin 250 at A
that says Ip route network y to pix A admin 250, the BGP network statement
for y that was
configured on router A kicks in, and we have a problem.
so what do you guys think, how can we solve this issue?
