port channel as a layer 3 interface

Unanswered Question

I have just inherited a very complex network and noticed in the config, for a cat-6513 with layer 3, the following:

interface Port-channel34

ip address 10.20.4.10 255.255.255.252


What would be a rationale for making a port-channel a layer 3 port?


thanks.

Have you ever configured a multilink ppp interface?

in the case of a portChannel as an L3 entity, it allows for the added capacity/redundancy of the link as well as provides the layer 3 topology either wanted or in some instances, required, such as when you need to make a multilink connection to a router from your switch.


or perhaps you have a routed core infrastructure created in your L3 environment and you wish to increase the capacity of the links between devices without using VTP/trunking.

Thanks for your response. Would it be possible to point me to a doc discussing this feature? Thanks again
