Some guy configured a Cat 6500 Core Switch on my net to handle MPLS traffic (and it works). The MPLS line is also directly connected to the internet, so our edges and firewalls are bypassed actually. I also have a 2851 router (IOS 12.4) router on my edge and want it to handle the MPLS traffic, but I'm stuck with the config. To me it looks something is wrong with the tunneling.

This is the working configuration of my 6500 Core Switch: (irrelevant configuration is omitted)

interface GigabitEthernet1/7
 ip address 10.24.17.254 255.255.255.252

interface Tunnel2
 ip address 192.168.250.1 255.255.255.0
 tunnel source 10.24.17.254
 tunnel destination 10.7.32.254

interface Tunnel3
 ip address 192.168.249.1 255.255.255.0

The same configuration was applied to the router, but it simply doesn't work. We want to connect our 2851's fastport 0/3 to WAN directly instead.

Our topology: Router 2851 -> PIX 525 Firewall (It's a dinosaur? Yes I know that) -> 6500 Catalyst Core Switch

Note: Our side of the MPLS is 10.24.17.254

  • Is the 2851 replacing the 6500 for access to the MPLS network? – user48838 Aug 7 '11 at 19:20

There is typically a BGP configuration for the MPLS network access. The configuration example does not include one, is that somehow missing?
