CR00023554 PRI 2 Previously, a PRI interface could lock up in the presence of line noise. This
has now been fixed.
YYYYY––––––
CR00023842 DHCP 2 Previously, on a router or switch using multihoming, the DHCP server on the
router or switch could sometimes assign multiple IP address to the same
client. This occurred for clients attached to an interface configured with
more than one IP address.
Some improvements to this issue were made in software version 2.9.1-16.
This software release resolves this issue. It ensures that DHCP release,
renew, and discover messages are correctly processed on interfaces with
multiple IP addresses, so that the DHCP server can identify when it has
already assigned a client an IP address.

CR00023921 RIP 2 Previously, RIP would not advertise the default route if a blackhole route
had been entered into the routing table. This was caused by RIP suppressing
the advertised routes based on the routes' netmask lengths instead of their
preference values. This has been fixed.
Please note that if your configuration relied solely on the netmask to
determine if a black hole route suppressed a route advertised by RIP, you
may need to have the routes' preference values adjusted so that it
continues to be suppressed.
YYYYYYYYYYY
CR00024189 PIM 2 Previously the router or switch may have restarted if a change in unicast
routing information led to a PIM Source, Group entry to no longer have an
RPF interface to a source.
This issue has been resolved.
