[j-nsp] GRE tunnel between PE-PE over non-MPLS core

[Cliff DeGuzman]

Bei,
 
Vpn routes use table inet.3 for next-hop resolution.  What does "show
route table inet.3" give you?

	Hi,

	 

	Have anyone used GRE tunnel bwteen PE-PE over non-MPLS core? I
encountered an issue that the VPN routes are been added to routing
table, but not installed in the forwarding table. Has anyone seen this
issue before? Thanks.

	 

	The VPN route 10.255.70.154 learned from far end PE is installed
in the routing table, but not installed in the forwarding table.
