LACP Bundle-ID numbers matching?

[Poppa Don]

Hello all,

I was wondering if when connecting multiple physical ports that are bundled via Ether-channel, LACP, if the bundle interface number must be the same on both devices?

I am working on an ASR9K so my side looks like this:

interface Bundle-Ether666
description BUN-666
ipv4 mtu 1500
ipv4 address 172.16.0.1 255.255.255.252
no shut
!
interface TenGigE0/0/0/1
description BUN-TEN-GIG BID:666-1
bundle id 666 mode active
lacp period short
load-interval 60
transceiver permit pid all
no shutdown
!
interface TenGigE0/0/0/2
description BUN-TEN-GIG BID:666-2
bundle id 666 mode active
lacp period short
load-interval 60
transceiver permit pid all
no shutdown
!

My primary question is whether or not the connecting router's configuration MUST also use 666 as their bundle ID? Or, can they use any other number, as if all of the physical ports were access ports?

Thanks,

Don

Hi Don,

The two routers connected to each other using Bundle ether port may use different ids as they are locally significant.We have about 100s of ASR9Ks and sometimes it is not possible to match the BE ids at both end and still it works like gem !
