Patch 86222-21 For Rapier Switches and AR800 Series Modular Switching Routers

7

PCR: 02287

Module: IPG

Network affecting: No

Existing IGMP groups were not deleted when IGMP was disabled globally or on the associated interface. This gave the groups very high timeout values. This issue has been resolved.

PCR: 02299

Module: VRRP

Network affecting: No

If a packet with a destination IP address equal to a VRRP IP address was received when the router didn’t own the IP address, (because it didn’t have an interface with that IP address) the router incorrectly tried to forward the packet and send an ICMP “redirect” message to the source. Now, if such a packet is received, it will be discarded and an ICMP “host unreachable” message will be sent to the source.

PCR: 02304

Module: VRRP

Network affecting: No

VRRP used the wrong source IP address in ICMP redirects. RFC 2338 states that the source IP address of ICMP redirects should be the IP address that the end host used when making its next hop routing decision. In the case of a packet sent to a VRRP virtual MAC address, this is the primary VRRP IP address associated with the MAC address, provided such a VR exists and is in the master state. This issue has been resolved.

PCR: 02317

Module: IPG

Network affecting: No

The SIZE functionality on the IP filter was not working for IP fragmented packets. This issue has been resolved.

Patch 86222-19 includes all issues resolved and enhancements released in previous patches for Software Release 2.2.2, and the following enhancements:

PCR: 02018

Module: OSPF

Network affecting: No

When OSPF was calculating routes from an AS external LSA and the AS external router had two next hops with different metrics, the router erroneously added two routes instead of one route with the best metric. This issue has been resolved. Also, when the two equal cost routes were on the same IP interface, but to different next hops, the router sent the packets to the wrong MAC address. This issue has been resolved.
