BGP ECMP

[Shobin Scaria]

I am looking for a help on configuring ECMP configuration on ASR 1001X

Device Details:

System image file is "bootflash:/asr1001x-universalk9.16.09.03.SPA.bin"

cisco ASR1001-X (1NG) processor (revision 1NG) with 6925454K/6147K bytes of memory.

We have multiple VRF in our router and forming eBGP with Service provider and AWS.

Here we are looking to configure the ECMP with AWS – which command we can use under IPv4 address family

router bgp 65123

address-family ipv4 vrf <ABC>

  maximum-paths 2

  maximum-paths eibgp 2

!

Which command should use – NOTE we are not configured any iBGP on this device for now

Second – Am I missing any additional command to configure ECMP on BGP

Hello Shobin,

router bgp 65123

address-family ipv4 vrf <ABC>

maximum-paths 2

>>maximum-paths eibgp 2

the last command should make the required job for you but remote PE loopback addresses  should be with equal cost in IGP metric otherwise the command  might become not effective.

Hope tp
