MPLS TE tunnel not coming up - RSVP issue?

dodgerfan78

Level 1

Hello,

I have two routers R2 and R5 back to back and I am trying to create an MPLS TE tunnel between them. R2 already has one tunnel up and running to another router R1.

I think my issue is that no RSVP traffic is being sent by R2 or R5. Here is my interface config on R5 and some show commands:

R5#show run int s2/0

Building configuration...

Current configuration : 143 bytes

!

interface Serial2/0

ip address 192.168.25.5 255.255.255.0

mpls traffic-eng tunnels

fair-queue 64 256 32

ip rsvp bandwidth 1000 1000

end

R5#show ip int brief s2/0

Interface IP-Address OK? Method Status Protocol

Serial2/0 192.168.25.5 YES NVRAM up up

R5#show ip rsvp counters in s2/0

Serial2/0 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#

I have mpls traffic-eng tunnels on all routers and interfaces. Here here is my tunnel config on R5 towards R2:

R5#show run int tun 2

Building configuration...

Current configuration : 174 bytes

!

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

I also am learning all addresses via OSPF so R5 does have a route (and can ping) 10.0.0.2 (R2's loopback)

Any ideas where this is failing? Why isn't RSVP sending packets?

Thanks,

u can see tunnel1 config that in both configuration two of command r not comming up same

interface Tunnel1

ip unnumbered Loopback9

tunnel destination 192.168.1.5

tunnel mode mpls traffic-eng

tunnel mpls traffic-eng autoroute announce

tunnel mpls traffic-eng priority 1 1

tunnel mpls traffic-eng bandwidth 50

tunnel mpls traffic-eng path-option 10 dynamic

>>> tunnel mpls traffic-eng auto-bw frequency 600

no routing dynamic

end

i want to set frequency time 10 min and tunnel max n min bandwidth that should change according to tunnel adjustmen after frequency but these both command not coming up at same time. i have done sumthin wrong?

hello my freind i dont know that much about TE but in ur tunnel interface commands u have nt put auto route announce command---> tunnel mpls traffic-eng autoroute announce

interface Tunnel1

ip unnumbered Loopback1

tunnel destination 192.168.1.3

tunnel mode mpls traffic-eng

tunnel mpls traffic-eng autoroute announce <--this command is very important)

tunnel mpls traffic-eng priority 1 1

tunnel mpls traffic-eng bandwidth 300

tunnel mpls traffic-eng path-option 10 dynamic

!

cus ur data cant route if it doesnt know the route. might be it can problem--

static

policy base

auto route
