MPLS
PD4-486972363 Bandwidth for the detour LSPs are calculated from the PLR node to the egress node, and
not from the PLR node to the MP. Therefore, detour LSP is signaled only when there is
enough bandwidth that is equal to or greater than the requested bandwidth for the detour
LSP from the PLR node to the egress node.
PD4-1072411171 Performing an SNMP get on vplsConfigVpnId may return the same value when configuring
a larger pseudo-wire ID value.
PD4-1329832557 An EXP examination and replacement configuration is retained after a user deletes MPLS
from a current VR and adds it to another VR.
Workaround: Use the unconfigure MPLS command before deleting MPLS from the VR
that is currently running MPLS, then add MPLS to a different VR.
PD4-822663105 Uploading or downloading a configuration results in an MPLS configuration being lost as
MPLS is not deleted from the VR-Default.
PD3-208178928 Adding a static route with an MPLS LSP may cause one of the following problems:
• If a static route is added with an MPLS LSP whose transport setting is “IP traffic deny,”
the route is displayed with an invalid nexthop in the show iproute mpls command
output.
• When a static route is added with an MPLS LSP that is not present in show iproute
mpls command output. For example, if there are 17 RSVP-TE LSPs to the same
destination, only 16 LSPs are eligible for carrying traffic because of a maximum ECMP
path limit of 16. Adding static routes with 17 LSPs results in the same observation.
Multicast
PD3-2841008 With PIM, when small-sized multicast streams are ingressed at line rate, there is an initial
packet drop of 50% to 70%. This is seen on BlackDiamond 8800 and Summit X450
switches.
PD4-901778542 The command mrinfo <neighbor ipaddress> from <source ipaddress> is not
displaying the entire interface when the source IP address is changed.
Spanning Tree Protocol
PD4-1161434651 MSTP edge ports are not correctly learning MAC addresses.
Workaround: To clear the wrong MAC address learned on the edge port, run the clear
fdb command. You may also wait until the FDB is automatically refreshed (default refresh
value is 300 seconds).
PD4-1238838391 Process stp signal 11 code: Program terminated with signal 11, Segmentation fault.
PD4-492384091 When scaled to the maximum number of Rapid Spanning Tree Protocol (RSTP) domains
with EMISTP port mode, an IGMP packet loops for a short period of time when a link flap
occurs.
