[c-nsp] ASR-1001 bgp memory usage

[Christian Kratzer]

Hi,

we have a pair of ASR-1001 taking a full bgp feed ipv4 and ipv6 from our upstream. We will have a second and third full feed soon and are quite a bit surprised by the memory usage of the first full feed.

     Router-1#show memory
 		    Head    Total(b)     Used(b)     Free(b)   Lowest(b)  Largest(b)
     Processor  7FC5CB741010   1235972656   884561540   351411116   350518960   350730684
      lsmpi_io  7FC5CAEE61A8     6295128     6294212         916         916         916

I doubt we will fit a further 2 full feeds into that remaining 350 MB.

An old 2821 only used up 300 MB for one and a half full feeds. This box seems quite thirsty.

The other router that is currently idle and not yet in the iBGP mesh already has on offset of 380MB.

     Router-2#show memory
 		    Head    Total(b)     Used(b)     Free(b)   Lowest(b)  Largest(b)
     Processor  7FBD6A7E2010   1235972656   387423056   848549600   817362160   816870148
      lsmpi_io  7FBD69F871A8     6295128     6294212         916         916         916

show versions shows this beast has 4GB memory of which the IOS process seems to use 1G

     cisco ASR1001 (1RU) processor with 1207124K/6147K bytes of memory.
     9 Gigabit Ethernet interfaces
     32768K bytes of non-volatile configuration memory.
     4194304K bytes of physical memory.
     7782399K bytes of eUSB flash at bootflash:.

I am currently not sure if I can assign the IOS process more memory somewhere or how I could check how the available memory is distributed to the subsystems or even if I have dual IOS processes running.

Any pointers ???

Greetings
Christian
