Traceback shows: 1#9ef25813351d0da79497b4305144eadc :10000000+5A9860 :10000000+5A9BE4 :10000000+10B9CA0 :10000000+10BEF34 :10000000+421761C :10000000+2AD6FC :10000000+2ADA28 :10000000+2FA91C :10000000+2FAF84 :10000000+2E748C Exception to IOS Thread: Frame pointer 35233FD8, PC = 1027203C ASR1000-EXT-SIGNAL: U_SIGSEGV(11), Process = BGP Router -Traceback= 1#9ef25813351d0da79497b4305144eadc :10000000+27203C :10000000+271DAC :10000000+273218 :10000000+2741B8 :10000000+33AE64 :10000000+33B5C4 :10000000+291D2C :10000000+2921C8 :10000000+2928AC Conditions: The symptom is observed whenever an old style multicast update is received and it uses the same AF value as that for VPNv4. Cisco IOS Release 12.2(33)XNE has code that detects this behavior, hence the traceback.
