Patch 86251-08 for Software Release 2.5.1
C613-10356-00 REV I
The ADD IPV6 HOST command was not accepting the INTERFACE
parameter when adding a host with a link-local address. This issue has been
resolved.
TCP did not send a TCP Reset message under some circumstances, for
example when the Telnet server was disabled. This issue has been resolved.
If ingress filtering was supported within trunk groups, ports with ingress
filtering enabled were erroneously added to the trunk group. This issue has
been resolved.
Some change actions, and the resending of prune messages were not
operating correctly. This issue has been resolved.
The test facility was not testing switch ports. This issue has been resolved.

ICMP Router Discovery Advertisements
Support for Router
Discovery
This release supports all of RFC 1256, ICMP Router Discovery Messages, 1991 as
it applies to routers. If this feature is configured, the router sends router
advertisements periodically and in response to router solicitations. It does not
support the Host Specification section of this RFC.
Benefits Before an IP host can send an IP packet, it has to know the IP address of a
neighbouring router that can forward it to its destination. ICMP Router
Discovery messages allow routers to automatically advertise themselves to
hosts. Other methods either require someone to manually keep these addresses
up to date, or require DHCP to send the router address, or require the hosts to
be able to eavesdrop on whatever routing protocol messages are being used on
the LAN.
Router Discovery
Process
See Table9 on page 48 for a summary of the processes that occur when Router
Discovery advertisements are enabled for interfaces on the router.
