BGP with Port Channel on Nexus 3k switch

navkatu1
Level 1
Level 1

\Hi Team,

 

Is there a method to add an additional 10G link to an in-production 10 gig link to form a port channel.

 

Nexus 3K switch is having BGP with one of the router over L3 port. We are advertising and receiving the routes via with EBGP.

Now we almost exhaust the 10G link so we need to add one more 10G link with port-channel configuration.

 

Note : One of Nexus 3k 40G port is converted into 4*10G ports and for current setup we want to use Eth 1/49/2 for new 10G link. Can we configure port channel between eth 1/49/1 & 1/49/2 (10G Converted ports).

 

Current Config :

Nexus 3K :

interface Ethernet1/49/1
description ~Connected to Router A
no switchport
speed 10000
duplex full
ip address 10.254.0.30/30
no shutdown

 

router bgp 64997
router-id x.x.x.x
log-neighbor-changes
address-family ipv4 unicast

neighbor 10.254.0.29 remote-as 100
address-family ipv4 unicast
route-map from-lon04-peer-a out

 

Proposed Config : 

interface Ethernet1/49/1
description ~Port-channel1
no shutdown

Speed 10000

channel-group 1 mode active

 

interface Ethernet1/49/2

description ~Port-channel1
no shutdown

Speed 10000

channel-group 1 mode active

 

Interface Port-channel 1

no  switch port

ip address 10.254.0.30/30

no shut

 

router bgp 64997
router-id x.x.x.x
log-neighbor-changes
address-family ipv4 unicast

neighbor 10.254.0.29 remote-as 100
address-family ipv4 unicast
route-map from-lon04-peer-a out

 

Can anyone suggest will it work ?

 

Thanks in advance

is this vPC ?

 

i do not see any issue, but when you move from standalone port to ethernet channle Layer 3, you will have link convergency, that time you have BGP flap and reconvegence take place.
