Dual IOSd processes in ASR1000 SW redundancy result in both the active and standby process
having access to about 750MB of RP memory (each); what is left is used by other RP
processes. Check "sh platform soft status contr" for more details about RP mem usage.
Regarding the SBC thing... i had the same problem...but i haven't got any
answer yet.
PS: To be honest, i haven't found any real advantage of sw redundancy yet. I only met more
issues.

Hi,
We use ASR 1004 for internet peering. I've noticed that despite the
fact that the device should have 4G of RAM (2G for each IOS), it only
reports about 750M:
cisco ASR1004 (RP1) processor with 750908K/6147K bytes of memory.
10 Gigabit Ethernet interfaces
1 Ten Gigabit Ethernet interface
32768K bytes of non-volatile configuration memory.
4194304K bytes of physical memory.
Why is there such a huge difference?
Other thing that I've noticed - after bringing first full feed the
free memory dropped by almost 300M, after bringing two more peers
we're down another 200M, even though the BGP summary doesn't reflect
that:
BGP router identifier 172.16.31.212, local AS number axaz
BGP table version is 1499020, main routing table version 1499020
319336 network entries using 45345712 bytes of memory
1754099 path entries using 119278732 bytes of memory

18 BGP extended community entries using 608 bytes of memory
0 BGP route-map cache entries using 0 bytes of memory
0 BGP filter-list cache entries using 0 bytes of memory
BGP using 207780318 total bytes of memory
853191 received paths for inbound soft reconfiguration
BGP activity 451647/132207 prefixes, 2813379/1059265 paths, scan
interval 15 secs
And the last thing - there seem to be a lot of memory allocated to the
SBC process:

How can i claim that memory back?
kind regards
