Three routers A, B, C
_____________
/ A \
/ \
| |
\ ospf 0 /
\ /
\ B C /
-----------
| EIGRP 50 |
-----------
Router A - S0 in ospf area 0
Router B - S0 in ospf area 0
Router C - S0 in ospf area 0
Router B - E0 in Eigrp 50
Router C - E0 in Eigrp 50
Redistribute between ospf and Eigrp such that
1) C should always chose B as its default connection unless the connection between B and A is down, then it should choose A.
2) B should always chose A as its default connection unless the connection to A is down, then choose C.
So far I have figured out all except for the connection going down between B and
A.
I used some AD manipulation and redistributing loopbacks to achive most of the result.
But there is one part that I haven't been able to achive .i.e when the connection between B and A is down, then C should A to send traffic.
Is there some way to adjust routing protocol behaviour when an interface goes down.
I remember working with ISDN demand circuits but don't think it will work in this case.
Any one want to take a crack at it.
By the way, router A is an ABR so there are routes being sent from other areas to area 0.
TIA
