ASR9K bundle-ether question

[exceedlizhihua]

hi guys,I have a question need confirm,could some friends help me.

the topology is like this

1 .does this portchannel support or not ,I mean ASR9001 side is router subinterface,C4500X side is SW trunk interface

2.if this portchannel is support,could i use lacp mode active ?(the old cisco router is not support lacp mode active like this case,only can use on mode)

Thank you very much.

Yup this is very much supported and I would recommend to use the option of running lacp for member management.

mode-on means that all members are hard inserted in the bundle with no state control. mode active means that you are running lacp and negotiate with the peer the member state and inclusion in the bundle.

on the a9k side you need to define EFP's or subinterfaces in order to peel out the different vlan's for either use as a routed interface or for insertion into a bridgedomain or xconnect.

Mr.Thuijs,thanks for your kindly support.

and I don't want use EFP,I want use the traditional configuration(put the ASR9001 interface into the bundle,and config the subinterface on the bundle),it's work,right?

[xthuijs]

yup no problem! here is an example:

!define member:

int te 0/0/0/0

bundle id 100 mode act

!instantiate the bundle master, this number must match the id of the member

int bundle-e100

!define the vlan subinterface with an ip address

int bundle-e100.10

encap dot1q 10

ipv4 add 1.2.3.4 255.255.255.0

cheers
