Two tunnel is configured on a router the source and destination of the tunnel is on one destination
And we have one vrf That one of these tunnels inside to vrf
And dynamic routing configure On two tunnels
But one of tunnel down then when configure mode ipip on one of tunnel is becomes up
what is the problem???
Router-2
interface Tunnel3
ip vrf forwarding src
ip address 10.10.23.2 255.255.255.0

eigrp must be also in VRF since the tunnel is VRF.

You should use a different src/dest pair for each tunnel. Configure a separate loopback interface for each tunnel and use it as the source.

Hello,
I lab tested this, looks like the route replication marked in bold brings all tunnels up. I have made some assumptions about the rd values being used, but give the below a try:
Router-2
ip vrf ali
rd 2:2
--> route-replicate from vrf src unicast all
--> route-replicate from vrf global unicast all
!
ip vrf src
rd 1:1
--> route-replicate from vrf ali unicast all
--> route-replicate from vrf global unicast all
Router-3
ip vrf ali
rd 2:2
--> route-replicate from vrf global unicast all
