Cisco Bug: CSCvr97348 - fib_manager crash after executing show cef <prefix>command when 64 path ECMP is enabled
Oct 23, 2020
- Cisco Network Convergence System 5500 Series
Known Affected Releases
Symptom: The fib_mgr crashed after executing show cef command when 64 ECMP paths are enabled and 8 ECMP paths resolving over it recursively. Following case caused the issue: service route - > 8 BGP paths - > each 8 BGP paths going over further 64 ECMP paths Conditions: 64 ECMP paths are enabled and 8 ECMP paths resolving over it recursively. So prefix resolving over 8 ECMP paths results into 8* 64 = 512 paths. For such prefix if "show cef <prefix> detail" command is executed then process fib_mgr crashes.
