Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• The PE does not map IP DSCP to the MPLS experimental field in the output interface. By default,
the router copies the three most significant bits of the DSCP of the IP packet to the EXP field in the
MPLS shim header. This problem is resolved in Release 12.1(20)E. (CSCea87671)
• OSM interfaces may stop receiving data after an RPR+ switchover. This problem is resolved in
Release 12.1(20)E. (CSCeb42402)
• For virtual private dial-up networks (VPDN), when an L2TP access concentrator (LAC) negotiates
an authentication protocol that is not listed as a valid authentication protocol according to the L2TP
Network Server (LNS) configuration, the LNS incorrectly accepts the negotiated options and uses
the authentication protocol set by the LAC. This problem is resolved in Release 12.1(20)E.
(CSCdz83019)
• EoMPLS VCs flap on an 8-port, 8 Gbps customer edge-to-provider edge (CE-to-PE) router
connection between WS-X6516-GBIC and OSM-2+4GE-WAN+ modules. This problem is resolved
in Release 12.1(20)E. (CSCeb04954)
• The FIB on an OSM might not be synchronized with the FIB on the MSFC. This problem is resolved
in Release 12.1(20)E. (CSCeb52142)
• When an OSPF topology change occurs, an MPLS provider edge (PE) router might not forward
IP-to-Tag traffic to some IP destinations when it has equal cost load-sharing paths to the IP
destinations. This problem is resolved in Release 12.1(20)E. (CSCeb52169)
• The set mpls exp and set ip precedence commands are not supported with basic MPLS and MPLS
VPN. This problem is resolved in Release 12.1(20)E. (CSCin43408, CSCeb25018)
• An E3 link to an OC-12 channelized OSM might not come up. This problem is resolved in
Release 12.1(20)E. (CSCec39689)
