Router Access and Default Router
Selection
Routing traffic between destinations on different VLANs configured on the
switch or to a destination on an off-switch VLAN is done by placing the switch
on the same VLAN interface or subnet as an IPv6-capable router configured
to route traffic to other IPv6 interfaces or to tunnel IPv6 traffic across an IPv4
network.
Router Advertisements
An IPv6 router periodically transmits router advertisements (RAs) on the
VLANs to which it belongs to notify other devices of its presence. The switch
uses these advertisements for purposes such as:
■ learning the MAC and link-local addresses of IPv6 routers on the VLAN
(For devices other than routers, the switch must use neighbor discovery
to learn these addresses.)
■
building a list of default (reachable) routers, along with router lifetime
and prefix lifetime data
■ learning the prefixes and the valid and preferred lifetimes to use for
stateless (autoconfigured) global unicast addresses (This is required for
autoconfiguration of global unicast IPv6 addresses.)
■
learning the hop limit for traffic leaving the VLAN interface
■ learning the MTU (Maximum Transmission Unit) to apply to frames
intended to be routed
Switch(config)# show run
Running configuration:
. . .
vlan 10
name "VLAN10"
untagged A1-A12
ipv6 address fe80::127 link-local
ipv6 address 2001:db8::127/64
ipv6 address autoconfig

Statically configured IPv6 addresses
appear in the
show run output.
Commands for automatic IPv6 address
configuration appear in the
show run
output, but the addresses resulting from
these commands do not appear in the
output.
