Basic MPLS

dangal.43 · ‎05-25-2007

we have two types of MPLS one is with the Port mode and other is with the Platform mode (router mode). So what are the main deference between both.

Is that good to use the OSPF Fast hello in Provider network with all router having Gigabyte Ethernet port and running MPLS?

MPLS operationally will function same as regardless the way it is implemented. Today IOS supports following mechanisms:

- In global cfg mode

- Per intf basis

following url has better explanation:

- LDP autocfg - enables you to globally configure LDP on every interface associated with a specified IGP instance.

And OSPF Fast-Hello is designed to provide fast convergence in the network, carefully designed timer parameters delivers optimal network convergence...

rahul,

it means if i will configure the OSPF fast hello on MPLS network it will not affect theperformance of the MPLS network.... but will help in fast convergence, right!!!

That is correct...

thanks,

rahul.
