Hello group, I need help in order to calculate the memory needed to accomodate 2 or more Full BGP Feeds. This is for a 12400 running IOS. Today i saw this problem with some linecards:
++++++++++++++++++++++++++++++ %FIB-2-FIBDISABLE: Fatal error, slot X: no memory ++++++++++++++++++++++++++++++ %HW_RES_FAIL-4-LOW_CEF_MEM: SLOT Y is running low on E4_Lookup External SRAM resources. CEF will begin resource constrained forwarding operation if problem persists. For additional details please see show ip cef resource and show ip cef summary %LC-3-HWRESFAIL: OUT OF HW RESOURCES - FORWARDING MAY NOT BE ACCURATE.PLEASE CORRECT THE SITUATION AND TRY CLEAR CEF LINECARD TO RECOVER ++++++++++++++++++++++++++++++ Slot X is a GE-GBIC-SC-B with 256 Mb of RAM and Slot Y is a 1X10GE-LR-SC with 512 Mb of RAM. The errors above occurred after the 2nd Full BGP Feed was received. Linecards 4GE-SFP-LC with 512 Mb of RAM did not complain. Neither the SIP-600 with 1 Gb or the SIP-601 with 2Gb. I have a PRP-2 with 1 Gb of RAM. I understand that 256 Mb is definitely not enough. But i don't understand why the problem only affected the 1X10GE-LR-SC and not the 4GE-SFP-LC. Both have 512 Mb of RAM. Thanks.
