Apologies for the very basic diagram. I am trying to get MPLS FRR working in my lab and have a couple of questions
The 7200 routers do support MPLS FRR whereas the 2621XM routers support MPLS TE but not MPLS FRR.
1) With the equipment shown in the diagram will it work. I read in one of the Cisco docs that the tail-end router also needs to support FRR but i'm not entirely sure what router they are referring to.
2) All the connections are ethernet.
Without FRR ie.
tunnel100 is just another tunnel and fa0/1 is not configured with the "mpls traffic-eng backup-path tunnel 100" when I shut down int fa0/1 then traffic goes via tunnel 100 as expected.
While it is switching across i get 1 or 2 "request timed out" on my pings.
3) I'm assuming that if i can get FRR working i shouldn't lose any pings - is that correct ?
When i do configure FRR ie.
tunnel mpls traffic-eng fast-reroute
mpls traffic-eng backup-path tunnel100
and then shut down fa0/1 i still get 1 or 2 "request timed out". When i do a
"sh mpls traffic-eng fast-reroute database" this is the output i get
7206vxr2#sh mpls traffic-eng fast-reroute database
Tunnel head end item frr information:
Protected tunnel In-label Out intf/label FRR intf/label Status
Prefix item frr information:
Prefix Tunnel In-label Out intf/label FRR intf/label Status
LSP midpoint item frr information:
LSP identifier In-label Out intf/label FRR intf/label Status
192.168.70.5 1  67 Fa0/1:25 Tu100:25 ready
There is no entry under the "Protected tunnel" line.
Could anyone help me on this.
