RE: GRT to VRF Communication

The problem sir is you are trying GRT to VRF via broadcast interfaces :)

Try using my method of loopback to loopback;

-OSPF is neighboring between two tunnel interfaces on same router
-Both Tunnel interfaces sourced from GRT
-Both Tunnel interfaces destined to GRT
-One tunnel is in GRT
-One tunnel is in VRF
-Performance tested at 50Mbps+ on 3845 between GRT and VRF

Hi,

I am stuck in enabling communication between GRT & VRF in 7609. I have tried
following thing but no success & I am stuck in a project migration b/c of
this. Any feedback would be appreciated.

RouterA:
int vlan10
ip add 1.1.1.1 255.255.255.0

int vlan 100
ip vrf forwarding CUST
ip add 2.2.2.2 255.255.255.0

ip route 2.2.2.2 255.255.255.255 vlan100
ip route vrf CUST 1.1.1.1 255.255.255.255 vlan10

arp 2.2.2.2 aa11.bb11.cc11 arpa
arp vrf SHARED 1.1.1.1 aa22.bb22.cc22 arpa

RouterA:
ping 2.2.2.2 source 1.1.1.1 (timeouts)
ping 1.1.1.1 source 2.2.2.2 (timeouts)

Regards,

Akhtar
