Hello everyone,
Other list members have a significantly lower memory usage for a BGP
process and a shmwin on ASR9001 routers with more sessions/routes in GRT.
Saku Ytti has suggested me some useful notes which I would like to mention
as a summary for this thread:
- one could use 'hw-module

All in GRT, 3 full tables, 2 big IX, couple private peers. No MPLS, only

Hello Alexandr,
Thank you for your input! We are using IOS XR 5.3.4 and 6.1.4 - no
significant difference in memory consumption between them.
How many peers/routes do you have on this box? Are those peers configured
in a GRT or in a VRF?

Hello Vladimir,
What version IOS XR are you using?
We are doesn't have problems with FIB inconsistency. IOS XR 6.6.3.

Hello everyone,
ASR9001 has some memory usage limits:
- 1658M for a BGP process on a RSP
- 1536M for a shared memory window on a LC
Those limits seems to be unconfigurable.
Has anybody experienced any issues with these limits on high-loaded ASR9001
boxes?
We have a surprisingly high memory usage
