Backing up VPN with DDR from different router

fisko — Fri, 21 Feb 2020 09:19:33 GMT

Hello!

I have the 3 routers A, B, and C.I build GRE tunnel between A and B and distribute EIGRP over GRE. So all 3 router have EIGRP connection.

How to confgure C router to backing up remote B router over ISDN with DDR and static floating when VPN between A and B goes down?

I try DDR with static floating, Here is the info

|-bri 172.30.1.0/24-RB-|

192.168.2.0/24RC-| 192.168.1.0/24

|-Tun 172.30.2.0/24-RA-|

Now I have

eigrp 20

network 192.168.0.0

network 172.30.0.0

on all routers

On Router B when i view

sh ip route 192.168.2.0 i see that goes over 192.168.1.1 that is ethernet ip of router A and that is correct.

I put on Router B

ip route 192.168.2.0 255.255.255.0 bri0 200

with access list for interesting traffic that deny eigrp for dialer

as soon as i enable bri0 interface on router B i get permanet route over bri0...

the eigrp route over router A dissapear and i dont have a connection to router C

How to tune eigrp in this case or what ever...

PS. I also have or Router C

ip route 192.168.1.0 255.255.255.0 200 bri0

and interesting traffic access list for dialer
