Hi group,
Let's assume following scenario:
RIP | EIGRP
R2
/ \
R1 R4
\ /
R3
R1 runs RIP, R4 runs EIGRP, R2 & R3 are running both, doing mutual
redistribution. Due to higher AD for external EIGRP, I don' t have to take
care of route reflection between protocols.
But now we redistribute network from loopback of R4 into EIGRP. R2 and R3
learn this route as external with AD 170. R1 also learns this network and
propagates it to R2 and R3. Result is that one of R2,R3 have route to R4'
loopback network through R1. The second have "proper" route through R4.
We could do route filtering, but what about situation when redistributed
networks can't be determined (eg. are injected from backbone?).
My idea was to tag routes from BB and filter them on R2 and R3 in RIP. But
it seems there is no method to filter advertisments by tag.
Any ideas?
