Re: DMVPN eigrp flap issue...

Hi ,

I am reaching the destination thru eigrp...

I am using eigrp on FR network to exchange the routing info between the
spokes.i removed eigrp from the FR and getting the following. I wish to keep
eigrp as the protocol for both dmvpn and FR cos I have seen it working on a
customer network...

HUB(config-router)#do sh ip eigrp ne
IP-EIGRP neighbors for process 10
H Address Interface Hold Uptime SRTT RTO Q Seq
Typ
e
                                            (sec) (ms) Cnt Num
1 10.0.0.2 Tu0 11 00:00:59 1 5000 1 0
0 10.0.0.3 Tu0 13 00:01:11 1 5000 1 0

retry limit exceeded message coming up...

How are you reaching the tunnel destination? Through EIGRP, another IGP or
static routes?

Hey Experts,

I need some valuable help from you on the scenario below:

1) I am working out dmvpn PHASE 1 on gns3.with 1 HUB and 2 spokes..

2)I have advertised 1.1.1.0 and 10.0.0.0 networks in eigrp

I have given "eigrp stub connected" on both the spokes.

MY eigrp neigh looks like this:

HUB#sh ip eigrp ne

IP-EIGRP neighbors for process 10

H Address Interface Hold Uptime SRTT RTO Q Seq

Typ

e

                                            (sec) (ms) Cnt Num

2 10.0.0.3 Tu0 11 00:00:12 1 5000 1 0

1 1.1.1.3 Se0/0.1 151 00:12:27 1 5000 0 14

0 1.1.1.2 Se0/0.1 142 00:12:51 372 2232 0 13

2)FR works fine but my neighborships flap like anything..

PLS LET ME KNOW IF YOU WANT ANY DEBUG OUTPUTS ON THIS SCENARIO....
