Hi, I am working on a solution to run mGRE for VRF-Lite. This is my situation: there are 5 sites currently connected by MPLS IPWAn provided by ISP. I want to run VRF-Lite throughout the network for path isolation between various VLANs. VRF-Lite works great within the site (Vrf-Lite end-to-end is being deployed). In order for to cross the IPWAN, mutipoint-GRE tunnels are being looked at. tunnels are getting created, but when advertised in the VRF routing process, neighbor is not being esablished. If I use the potint to point tunnel, neighbor relationship is estanblished, working as expected. The issue will be I need to create over 50 tunnels to achieve the expected results.
Can someone help me, if the mGRE with VRF-Lite is a feasible solution? Thanks in advance Shine ---------------------------- Following is a snippet of my configuration: Router 1 ======== interface Tunnel110 ip vrf forwarding Data ip address 10.40.61.1 255.255.255.224 no ip redirects ip nhrp map 10.40.61.2 172.16.123.2 ip nhrp map 10.40.61.3 172.16.123.3 ip nhrp network-id 110 ip nhrp cache non-authoritative tunnel source GigabitEthernet0/1 tunnel mode gre multipoint tunnel key 110 router eigrp 100 no auto-summary ! address-family ipv4 vrf Gorgon_Data network 10.40.61.1 0.0.0.0 no auto-summary autonomous-system 100 exit-address-family !
