CLI Procedures - IPv6 Static Routes

This section includes some basic procedures for managing static routes using the CLI.

To show IPv6 static routes, run

show ipv6 route static

Codes: C - Connected, S - Static, B - BGP, Rg - RIPng, A - Aggregate,

       O - OSPFv3 IntraArea (IA - InterArea, E - External),

       K - Kernel Remnant, H - Hidden, P - Suppressed

S     3100:55::1/64       is directly connected

S     3200::/64           is a blackhole route

S     3300:123::/64       is a blackhole route

S     3600:20:20:11::/64  is directly connected, eth3 

To add an IPv6 static route, run:

set ipv6 static-route <Destination> nexthop gateway <gw_ip> on
set ipv6 static-route <Destination> nexthop gateway <gw_ip> interface 
<gw_if> on

Destination - Destination IPv6 address.
gw_ip - Next hop gateway IPv6 address.
gw_ip - Next hop gateway interface name.

Example:

set ipv6 static-route 3100:192::0/64 nexthop gateway 3900:172::1 on
set ipv6 static-route 3100:192::0/64 nexthop gateway 3900:172::1 interface eth3 on

To add an IPv6 static route with paths and priorities, run:

set static-route <Destination> nexthop gateway <gw_id> priority <P Value>

Destination - Destination IP address.
gw_ip - Next hop gateway IP address.
P Value - Integer between 1 and 8 (default =1)

Run this command for each path, assigning a priority value to each. You can define two or more paths using the same priority to specify a backup path with equal priority.

Example:

set ipv6 static-route 3100:192::0/64 nexthop gateway 3900:172::1 priority 3 on

To add an IPv6 static route where packets are dropped, run:

set ipv6 static-route <Destination> nexthop reject

set ipv6 static-route <Destination> nexthop blackhole

Destination - Destination IP address.
Reject - Drops packets and sends an error message to the traffic source.
Blackhole - Drops packets, but does not send an error message.

Examples:

set ipv6 static-route 3100:192::0/64 nexthop reject

or

set ipv6 static-route 3100:192::0/64 nexthop blackhole

To delete an IPv6 route and all related paths, run:

set ipv6 static-route <Destination> off

Destination - Destination IP address.

Example:

set ipv6 static-route 3100:192::0/64 off

To delete a path only, run:

set static-route <Destination> nexthop gateway <gw_ip> off

Destination - Destination IP address.
gw_ip - Next hop gateway IP address or interface name.

Example:

set ipv6 static-route 3100:192::0/64 nexthop gateway 3900:172::1 off
