IPv6 anycast filtering
1
IPv6 anycast filtering
By default all IPv6 packets with anycast address as destination will be processed. The following
command provides options to selectively enable protocols or disable all protocols.
Brocade(config)# ipv6 anycast-no-response allow tcp
Syntax: [no] ipv6 anycast-no-response [allow ]
The allow tcp | udp | icmp specifies the protocol to allow for processing.
Note:
1. The allow options can also be used as standalone commands. If ipv6 anycast-no-response is
already configured, it is modified based on the specified filters.
2. User can enable generation of TCP resets for incoming TCP packets with destination set as
anycast address, by configuring ip tcp enable-reset command. However, if ipv6
anycast-no-response command is also enabled, this command becomes void since all anycast
packets are blocked. If user requires reset to be sent for incoming anycast TCP packets, user
has to configure ipv6 anycast-no-response allow tcp to unblock the incoming TCP packets.
