Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S
• CSCeg52659
Symptoms: A Cisco 7200 series may not withdraw a BGP route from an iBGP peer.
Conditions: This symptom is observed on a Cisco 7200 series that runs Cisco IOS Release 12.3(3)
when the clear ip /jointfilesconvert/415844/bgp neighbor-address soft out command is entered for one of the members of the
peer group of which the Cisco 7200 series is a member and when some changes to the outbound
policy are made to the same member of the peer group. This situation causes some prefixes to remain
struck in the other members of the peer group. The symptom may also occur in other releases.
The symptom is a very old behavior of the BGP peer group functionality: when one member of a
peer group is cleared via either a hard reset or a soft reset and a policy change causes some of the
prefixes to be withdrawn, inconsistencies may occur in the routes on the other members of the peer
group.
Workaround: For peer groups and neighbors that are members of a peer group, do not enter the BGP
neighbor-specific clear ip /jointfilesconvert/415844/bgp neighbor-address soft out command or the clear ip /jointfilesconvert/415844/bgp
neighbor-address command. Rather, enter the peer group-specific clear ip /jointfilesconvert/415844/bgp peer-group-name
soft out command or the clear ip /jointfilesconvert/415844/bgp peer-group-name command.
• CSCeg57155
Symptoms: A ping, Telnet traffic, FTP traffic, and trace route traffic across a VRF-aware NAT do
not function.
Conditions: This symptom is observed on a Cisco router that is configured for VRF-aware NAT only
when the router is not directly connected to a gateway.
Workaround: There is no workaround.
• CSCeh09588
Symptoms: During an NSF switchover on a RP, the convergence may be delayed up to five minutes.
Conditions: This symptom is observed when a DBD exchange error occurs while the adjacency is
brought up.
Workaround: Enter the clear ip ospf process command on the affected router.
• CSCeh15639
Symptoms: A Cisco router may crash when it is reloaded with PIM traffic on the network.
Conditions: This symptom is observed on a Cisco 7200 series router with multicast enabled but is
not platform dependent. Bootup is the most likely place where this will happen, but the router may
crash anytime if an interface flap happens at the right time while receiving PIM traffic.
Workaround: There is no workaround.
• CSCeh33504
Symptoms: A router terminates 102,000 VPNv4 routes but route reflectors (RRs) report only a a
subset of the total.
Conditions: This symptom is observed on a Cisco MGX RPM-XF that runs Cisco IOS
Release 12.3(11)T4 when 204 routes are configured per VRF over 496 VPNs (one VPN has about
1000 routes). However, Cisco MGX RPM-PRs that function as RRs show that only 76245 routes are
terminated on the Cisco MGX RPM-XF. The symptom is platform-independent and may also occur
in other releases.
Workaround: There is no workaround.
• CSCeh35246
Symptoms: A router may crash when a subinterface on which OSPF is running is deleted.
