Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
5. AAA receives a response from external AAA.
6. AAA passes the response to RADIUS LOCAL SERVER which transmits an Access-Accept or
Access-Reject to SESM.
If the processing delay of sum (C,D,E,F) is greater than the SESM timeout, SESM will send another
Access-Request with the same credentials for the Account logon postpaid user in B.
If this occurs, policy/AAA will now use this second Account-Logon request from SESM for this
user’s Account Login and the policy will not free the AAA request from the former Account Logon
request, hence the memory leak will present as RADIUS LOCAL SERVER.
Workaround:
1. Make sure SESM Account Logon Timeout > RADIUS timeout.
2. Decrease load on external AAA (RADIUS) machines.
CSCtc87700
Symptoms: A Cisco 7600 router may fail to process ingress Link Integrity Protocol messages on
MFR serial link members, which will disallow Multilink Frame Relay interfaces from enabling.
Conditions: This symptom occurs on a Cisco 7600 router with SUP-720-3BXL and OSM CHOC12,
and running Cisco IOS Release 12.2(33)SRC and 12.2(33)SRD. This issue happens when MFR
serial members are configured on CHOC12 OSM but may also occur on other line cards.
Workaround: There is no workaround.
CSCtc87822
Symptoms: On a PE router, eBGP-learned VRF routes might not be advertised to eBGP neighbors
in the same VRF.
Conditions: The symptom is observed if DUT first learns the route from IBGP-VPNv4 (same RD)
and then learns the route from the CE.
Workaround: Soft clear towards the CEs missing the routes.
CSCtc90579
Symptoms: Router crashes due to memory corruption during MPLS TE auto backup tunnel deletion.
Conditions: Caused by topology changes triggering backup tunnel deletion and RSVP hello
mechanism.
Workaround: Gloablly, disable RSVP hello and enable BFD hello:
Router(config)#no ip rsvp signalling hello
Router(config)#ip rsvp signalling hello bfd
Per MPLS TE enabled interface:
Router(config-if)#no ip rsvp signalling hello
Router(config-if)#ip rsvp signalling hello bfd
CSCtc94339
Symptoms: Multicast traffic is not forwarded in an egress direction via GRE over MPLS after a
switchover.
Conditions: The symptom is observed with GRE over MPLS with PIM enabled on the tunnel
interface, from a Cisco 7600 series router in SSO redundancy mode.
Workaround: Reload the router.
