I have been trying to configure a tunnel across multiple OSPF area on a
cisco network. I have been refering to the cisco docs that talk about
configuration of tunnels on multiple OSPF areas.
There was a section about configuring an Area Border router(ABR). My
question is if ABR a specialized piece of hardware or software patch
loaded ? I have an MPLS 3600 (IOS12.3) router in the border between ospf
areas. Its configured as follows
router ospf 1
mpls traffic-eng router-id Loopback0
mpls
traffic-eng area 0
log-adjacency-changes
network 10.225.48.0
0.0.0.255 area 0
network 10.225.50.0 0.0.0.255 area
0
network 10.226.0.0 0.0.0.255 area 6
network 10.226.1.0
0.0.0.255 area 6
network 10.226.127.33 0.0.0.0 area
6
network 10.224.0.0 0.31.255.255 area 0
!
Since this router is in between area 0 and 6 should I have another entry as
mpls traffic-eng area 6
when I do try to issue this above command, I get
%MPLS TE already enabled, on ospf area 0
Does that mean this router that I am using is not capable of being a ABR
?
(Cisco Docs Step 4 says I should issue the following commands.
Router(config-router)# mpls traffic-eng area 0
Router(config-router)# mpls traffic-eng area m
)
Thanks for your time.
