Configuring IPv6 IS-IS
Example
hostname R1
!
router isis
address-family ipv6
redistribute static
exit-address-family
net 49.0001.1921.6801.0001.00
!
interface fastethernet0/0
address 2001:410:ffff:1::1/64
ipv6 router isis
isis circuit-type level-2-onlyIPv6 IS-IS through IPv4 only islands
Because IS-IS uses CLNP and not IPv6 a standard IPv6-over-IPv4-Tunnelcan't be used. A GRE tunnel through IPv4 is necessary.
router isis
net 49.0001.1921.6801.0001.00
!
interface tunnel0
ipv6 address 2001:410:ffff:1::1/64
tunnel source ethernet0
tunnel destination 132.214.1.3
tunnel mode gre ipv6
ipv6 router isis
