Release Notes for BayRS Version 15.1.0.0

DVMRP Holddown Timer for Deleted Routes

To avoid problems that can occur when a route is deleted, DVMRP implements a

holddown timer (see draft-ietf-idmr-dvmrp-v3-10, section 3.4.8). During the

holddown period, the deleted route is advertised as unreachable, and all

forwarding cache entries based on the route are flushed. The holddown period

lasts for two route report intervals.

The Nortel Networks implementation of DVMRP now supports the holddown

timer for deleted routes. You can use the BCC or Site Manager to enable or

disable the DVMRP holddown timer on the router. If your router needs to be

backward compatible with older implementations of DVMRP, use the default

value (holddown disabled).

For more information, see Configuring IP Multicasting and Multimedia Services.

Exclusive Login Authentication via RADIUS

This feature enables a router to authenticate multiple users (with individual

profiles) via RADIUS. If authentication between the RADIUS client and server

fails, other means will allow access to the router via Telnet and console

connections. When the server is not reachable, the router will periodically attempt

to re-establish communications as configured.

For more information, see Configuring RADIUS.

Dropping IP Source Record Routing Packets

This feature provides an IP global parameter to enable (default) or disable IP

source routing for a router. When IP source routing is disabled, the router drops

loose source record route (LSSR) and strict source record route (SRRR) packets.

This feature provides greater network security to users of IP source routing.

For more information, see Configuring IP, ARP, RARP, RIP, and OSPF Services.
