Hello,
I have:
R1----R2----R5
I have a tunnel that is up from R1 to R2 yet the tunnel to R2 to R5 (both
ways) won't come up. I believe it is because R5 is not sending/receiving
RSVP messages. I an using loopbacks as tunnel endpoints, here are some show
commands:
*Config for s2/0*
R5#show run int s2/0
interface Serial2/0
ip address 192.168.25.5 255.255.255.0
mpls traffic-eng tunnels
fair-queue 64 256 37
ip rsvp bandwidth 1000 1000
end
*NO RSVP messages:*
R5#show ip rsvp counters summary
All Interfaces Recv Xmit Recv Xmit
Path 0 0 Resv 0 0
PathError 0 0 ResvError 0 0
PathTear 0 0 ResvTear 0 0
ResvConfirm 0 0 ResvTearConfirm 0 0
UnknownMsg 0 0 Errors 0 0
R5#
*Tunnel config:*
R5#show run int tun 2
interface Tunnel2
ip unnumbered Loopback0
tag-switching ip
tunnel destination 10.0.0.2
tunnel mode mpls traffic-eng
tunnel mpls traffic-eng path-option 1 dynamic
end
R5#show mpls traffic-eng link-management int s2/0
System Information::
Links Count: 2
Link ID:: Se2/0 (192.168.25.5)
Link Status:
Physical Bandwidth: 1544 kbits/sec
Max Res Global BW: 1000 kbits/sec (reserved: 0% in, 0% out)
Max Res Sub BW: 0 kbits/sec (reserved: 100% in, 100% out)
MPLS TE Link State: MPLS TE on, RSVP on, admin-up
Inbound Admission: allow-all
Outbound Admission: allow-if-room
Admin. Weight: 64 (IGP)
IGP Neighbor Count: 0
Flooding Status for each configured area [1]:
IGP Area[1]: ospf area 0: not flooded
(Reason: Link has no IGP adjacencies for this area)
R5#
R5#show ip ospf neighbor s2/0
Neighbor ID Pri State Dead Time Address Interface
10.0.0.2 1 FULL/ - 00:00:37 192.168.25.2 Serial2/0
Any idea why the 4th command shows 0 as the IGP neighbor count?
btw, I am following the troubleshooting chapter in Traffic Engineering with
MPLS book. I have removed all constraints except dynamic path option and
shut down all redundant links.
