Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Open Caveats—Cisco IOS Release 12.0(33)S
Conditions: This symptom is observed on a Cisco router that is configured for BGP.
Workaround: There is no workaround.
CSCsd54539
Symptoms: After the command route-map test-comm-in permit 20 is issued, one of the peers
should be denied and should not be advertised to any other peers.But this behavior is not seen with
this image.
Conditions: Occurs when the route map test-comm-in permit 20 is entered.
Workaround: There is no workaround.
CSCsg42672
Symptoms: On a Cisco router running Cisco IOS release 12.0(32)S4 and configured with BGP and
peer-groups, if the Fast Peering Session Deactivation feature is configured in the peer-group, the
router automatically configures on the command a route-map with the same name as the peer-group.
Conditions: Occurs when the following is configured:
RR#conf t
Enter configuration commands, one per line. End with CNTL/Z.
RR(config)#router /jointfilesconvert/415844/bgp 65001
RR(config-router)#neighbor rrs-client fall-over ?
bfd Use BFD to detect failure
route-map Route map for peer route
<cr>
RR(config-router)#neighbor rrs-client fall-over
RR#sh ru
<snip>
router /jointfilesconvert/415844/bgp 65001
neighbor rrs-client peer-group
neighbor rrs-client remote-as 20959
neighbor rrs-client update-source Loopback0
neighbor rrs-client fall-over route-map rrs-client <<<<<<<
the route-map does not exist.
Workaround: Configure the neighbor individually or use peer-templates
CSCsg48540
Symptoms: A carrier supporting carrier (CsC) Multiprotocol Border Gateway Protocol (MPBGP)
connection between two PE routers may remain in the active state but never becomes established.
Conditions: This symptom is observed when (CsC) is configured on all routers.
Workaround: There is no workaround.
CSCsi68795
Symptoms: A PE that is part of a confederation and receives a VPNv4 prefix from an internal and
an external confederation peer assigns a local label to the prefix despite the fact that the prefix is not
local to this PE and that the PE is not changing the BGP next-hop.
Conditions: Occurs when receiving this prefix via two paths from confederation peers.
Workaround There is no workaround.
Further Problem Description: Whether or not the PE will chose to allocate a local label depends on
the order at which the multiple paths for this vpnv4 prefix are learned. The immediate impact is that
the local label that is allocated takes up memory in the router as the router will populate the LFIB
with the labels.
CSCsj56281
Symptoms: Inherit peer-policy does not work after a router reload
