Why there are MPLS routes on my 7604 router?

[danielchau]

HI all,

I Have a 6509 router running in production environment, but I am planning to switch it to a 7604 router.

While I dont have the problem of the config between them, it seems that from a unknown reason, there is some MPLS routers that exists on the new router:

Here is the 6509 router output:

6509#show mls cef summary

Total routes:                                    636416
    IPv4 unicast routes:                         636393
        IPv4 non-vrf routes:                     636393
        IPv4 vrf routes:                         0
    IPv4 Multicast routes:                       4
    MPLS routes:                                 1
    IPv6 unicast routes:                         14
        IPv6 non-vrf routes:                     14
        IPv6 vrf routes:                         0
    IPv6 multicast routes:                       3
    EoM routes:                                  1

But on my 7604: (not in production)

7604#show mls cef summary

Total routes:                     2089
    IPv4 unicast routes:          29
    IPv4 Multicast routes:        4
    MPLS routes:                  2048
    IPv6 unicast routes:          8
    IPv6 multicast routes:        3
    EoM routes:                   0

I don&t understand why there are MPLS routes while i do not intentionally use, or enabled any vrf, or MPLS functions.

How can i know how this 2048 MPLS routes comes from?

Thanks

Daniel

Hi

Have you configured MP-BGP on your router? or have you established any mpls neighbor? 

show bgp vpnv4 unicast summary

show mpls ldp neighbor

Hi Julio,

Thanks, I dont think i have setup MP-BGP . I do have ISIS with BGP on the router.

Here is the result on my 7604 with the suggested commands:

7604#show bgp vpnv4 unicast summary
                                 ^
% Invalid input detected at '^' marker.

7604#show mpls ldp neighbor

7604#

Regards,

Daniel
