the next hop IPv6 address is global aggregatable unicast address and site-local address, if no
interface name of the exit is specified, it must be assured that the IP address of the next hop and the
address of some interface of the switch must be in the same network segment. As for tunnel route,
interface name can be directly specified.
Example:
Configure static route 1 with destination address 3ffe:589:dfc::88, prefix length 64 and next hop
2001:8fd:c32::99 (the router has been configured IPv6 address of 2001:8fd:c32::34/64).
Switch(config)#ipv6 route 3ffe:589:dfc::88/64 2001:8fd:c32::99
Configure static route 2 with destination 3ffe:ff7:123::55, prefix length 64, next hop
fe80::203:ff:89fd:46ac and exit interface name Vlan1.
Switch(config)#ipv6 route 3ffe:ff7:123::55/64 fe80::203:ff:89fd:46ac Vlan1
19.2.14 ipv6 redirect
Command:
ipv6 redirect
no ipv6 redirect
Function:
Enable IPv6 router redirect function. The no operation of this command will disable the function.
Command Mode:
Global Configuration Mode.
Default Settings:
IPv6 router redirect function is disabled by default.
Usage Guide:
If router A, router B, and node C are on the same network link, and router A forwards IPv6 packets
from node C to router B, expecting router B to continue the forwarding, then router A will send an
IPv6 ICMPv6 redirect message to node C-source of the packet, notifying it that the best next hop of
this destination address is router B. By doing so, the forwarding overhead of router A will be
decreased, so is the network transmission delay of node C.
Examples:
Enable IPv6 router redirect function.
Switch(config)# ipv6 redirect
