Hi.
Backbone network is running MPLS/VPN.
I have one VRF (VRF-A) for client VPN network.
One requirement is to configure another VRF (VRF-B) for this client for a separate public VRF connection.
Sub-interfacing not allowed on CE-to-PE due to access provider limitation.
So GRE is our option.
CE config:
Note: CE is running on global. VRF-A is configured at PE.
But will add VRF-B here for the requirement.
interface Tunnel0
ip vrf forwarding VRF-B
ip address 10.12.25.22 255.255.255.252
tunnel source GigabitEthernet0/1
tunnel destination 10.12.0.133
PE1 config:
interface Tunnel0
ip vrf forwarding VRF-B
ip address 10.12.25.21 255.255.255.252
tunnel source Loopback133
tunnel destination 10.12.26.54
tunnel vrf VRF-A
Tunnel works and can ping point-to-point IP address.
CE LAN IP for VRF-B is configured as static route at PE1
PE1:
ip route vrf VRF-B 192.168.96.0 255.255.255.0 Tunnel0 10.12.25.22
But from PE2 which is directly connected to PE1 (MPLS/LDP running), connectivity doesnt works.
From PE2:
- I can ping tunnel0 interface of PE1
- I cant ping tunnel0 interface of CE
Routing is all good and present in the routing table.
From CE:
- I can ping any VRF-B loopback interface of PE1
- But not VRF-B loopback interfaces PE2 (even if routing is all good)
PE1/PE2 are 7600 SRC3/SRD6.
Any problem with 7600 on this?
Need comments/suggestions.
