Hi,
What Brian hinted to is how we do it in our network. MPLS is only used for
EoMPLS/VPLS traffic,
the rest is routed via "normal" IP. We have dedicated /32s Loopbacks for the
EoMPLS/VPLS endpoints
and only traffic to those /32s are labeled and MPLS switched.
example config for /32 MPLS loopbacks out of 10.0.255.0/24:
configuration for all backbone routers:
access-list 1 permit 10.0.255.0 0.0.0.255
no mpls ldp advertise-labels
mpls ldp advertise-labels for 1 ! only advertise labels for addresses contained
in ACL 1
mpls label protocol ldp
additional loopback on edge routers where the EoMPLS/VPLS circuits terminate,
e.g.:
interface Loopback1
description MPLS loopback
ip address 10.0.255.10 255.255.255.255
mpls ldp router-id Loopback1 force

Chris

Hi,Brian
Thank you for your reply!but i think it can not meet the requirements for what
i need.
the traffic between two vpn sites will always follow the FEC and this command
can not distinguish them.

Hi,
As we know, if i enable mpls on the appropriate interface then the ip packets
will be forwarded based on mpls forwarding table not the ip forwarding
anymore.for some reason.my question is that is there any way to make the
ip forwarding on the interfaces which mpls enabled?
Not sure if this is what you want .. .but I think so ...
you can decide what to send labels for with filters using the command
mpls ldp advertise-labels
so what has a label is switched with mpls, what does not have a label uses ip
forwarding.
Regards,
Brian
