Hi all,
Currently we have one SCE8000 wich is implemented with following cheme: ASR9000 -> SCE -> ASR9000
We want to buy second SCE. Classical MGSCP design requires SCE single ASR9000 with SCE ports in different VRFs.
Is it possible to save current cheme with 2 SCEs? i.e.
-> SCE ->
ASR9000 ASR9000
-> SCE ->
Solved! Go to Solution.

Hello,
I guess there are ways to configure it :o), just ensure somehow that outgoing and incoming traffic for the same subscriber goes through the same SCE box.
If you use ether-channel load-balancing (bundle interface), one ASR has to use balancing based on sourceIP and another ASR based on destinationIP (basically, always use subscriber IP for ether-channel load-balancing hash).
It should resemble to this example, but vrf "core" and "access" are two separate ASR boxes in your scenario: http://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k_r4-1/interfaces/configuration/guide/hc41asr9kbook/hc41lbun.html#wp1044287

Thank you!
I assumed so too. But I needed opinion from knowing people.
Thanks again!
