IPv6 Over IPv4 tunnels in hardware
19
•
Static routes can be used with 6to4 tunnels. If you use a static route to configure the nexthop,
you MUST enable nexthop recursion in the system (ipv6 route next-hop-recursion).
•
The 6to4 tunnel tries to resolve all the nexthops and programs the cam and pram entries
needed. The IPv4 address in the nexthop should be reachable through the IPv4 network.
Example
In the below configuration:
•
10.10.10.1 is the tunnel source IP address
•
10.10.10.10 is the static nexthop
•
21.21.21.6 is I-BGP nexthop
•
22.22.22.6 is E-BGP nexthop
Static route Nexthop example:
•
Create a static route pointing to the tunnel.
Brocade(config) #ipv6 route 2002::/16 tunnel 2 // Mandatory for 6to4 Configuration
Brocade(config) #ipv6 route next-hop-recursion // Mandatory with static nexthop
Brocade(config)# ipv6 route 3001::/64 2002:0a0a:0a0a::1 // Static Nexthop:
10.10.10.10
•
Create a Source Interface - The remote node needs to have a similar route pointing to this
node.
Brocade(config)# interface ethernet 1/1
Brocade(config-if-e10000-1 /1)ip address 10.10.10.1 255.255.255.0
•
Create a 6to4 Tunnel configuration.
Brocade(config) interface tunnel 2
Brocade(config-tnif-2) tunnel mode ipv6ip 6to4
Brocade(config-tnif-1) tunnel source 10.10.10.1
Brocade(config-tnif-1) ipv6 address 2002:0a0a:0a01::1/64
Example : I-BGP Nexthop.
Brocade(config) router bgp
Brocade(config-bgp) local-as 100
Brocade(config-bgp) neighbor 2002:1515:1506::1 remote-as 100 // BGP Nexthop:
21.21.21.6
Brocade(config-bgp)# address-family ipv4 unicast
Brocade(config-bgp)# no neighbor 2001:DB8:1506::1 activate
Brocade(config-bgp)# exit-address-family
Brocade(config-bgp)# address-family ipv4 multicast
Brocade(config-bgp)# exit-address-family
Brocade(config-bgp)# address-family ipv6 unicast
Brocade(config-bgp)# neighbor 2002:1515:1506::1 activate
Brocade(config-bgp)# exit-address-family
Example : E-BGP Nexthop.
Brocade(config)# router bgp
Brocade(config-bgp)# local-as 100
Brocade(config-bgp)# neighbor 2002:1616:1606::1 remote-as 101 // BGP Nexthop:
22.22.22.6
Brocade(config-bgp)# neighbor 2002:1616:1606::1 ebgp-multihop
Brocade(config-bgp)# address-family ipv4 unicast
Brocade(config-bgp)# no neighbor 2002:1515:1506::1 activate
Brocade(config-bgp)# exit-address-family
Brocade(config-bgp)# address-family ipv4 multicast
