Release Notes for the Passport 8600 Release 3.7.6
VRRP
• VRRP hotstandby (with WebOS software version 10.0.29.0) is not supported
in this release. (Q00249554)
• Nortel Networks does not recommend using the same IP address for the
VRRP logical IP interface and the physical IP interface. (Q00812854)
Multicast
General
• The Multicast Router Discovery protocol could cause interoperability issues
on a Passport 8600 connected to other devices implementing this protocol,
because the Passport 8600 implementation sends Multicast Router Discovery
messages to the all routers address (224.0.0.2). Newer drafts define the
destination address as the all hosts address of 224.0.0.1. Devices
implementing Multicast Router Discovery protocol based on the latest drafts
interoperate with the Passport 8600 only if they are able to send and receive
Multicast Router Discovery messages using the 224.0.0.2 address.
(Q00309216)
• When you enter the CLI command
query max response, the switch sets
the wrong parameter value for an IGMPv3 interface. (Q00912706)
IGMP
• In an SMLT configuration, when multicast traffic ingresses on an IGMP
snoop-enabled edge switch from a PIM or a DVMRP-enabled IST switch,
show ip igmp sender CLI output always displays the IGMP Querier port
as the sender port even though data is actually ingressing on a different port of
the MLT. There is no traffic loss due to this issue. (Q00668314)
Caution: Do not perform management using the VRRP interface. Use
actual IP addresses for management purposes. (Q00971864)
