Policy-Based Routing Configuration Tasks
To enable IPv6 PBR on an interface, perform this task:
Command Purpose
Step 1
Switch(config)# route-map map-tag [permit |
deny] [sequence-number]
Defines a route map to control where packets are sent. This
command puts the switch into route-map configuration mode.
Step 2
Switch(config-route-map)# match ipv6 address
{access-list-number | name}
[...access-list-number | name]
Specifies the match criteria. The match criteria take the form
of one or more Standard or Extended ipv6 access-lists. The
access-lists can specify the source and destination IP
addresses, protocol types, and port numbers.
Step 3
Switch(config-route-map)# set ipv6 next-hop
ip-address [... ip-address]
Or
Specifies the next-hop IP address to which matching packets
are sent. The next-hop IP address specified here must belong
to a subnet that is directly connected to this switch.
If more than one next-hop IP address is specified, the first
usable next-hop is chosen for routing matching packets. If the
next-hop is (or becomes) unavailable for some reason, the
next one in the list is chosen.
Step 4
Switch(config-route-map)# set interface
interface-type interface-number
[... type number]
Or
Specifies the output interface from which the packet will be
sent. This action specifies that the packet is forwarded out of
the local interface. The interface must be a Layer 3 interface
(not a switchport).
Packets are forwarded on the specified interface only if one of
the following conditions is met:
• The destination IP address in the packet lies within the IP
subnet to which the specified interface belongs.
• The destination IP address in the packet is reachable
through the specified interface (as per the IP routing
table).
If the destination IP address on the packet does not meet
either of these conditions, the packet is dropped. This action
forces matching packets to be switched in software.k
Step 5
Switch(config-route-map)# set ipv6 default
next-hop ip-address [... ip-address]
Or
Sets next hop to which to route the packet if there is no
explicit route for the destination IP address in the packet.
Before forwarding the packet to the next hop, the switch looks
up the packet’s destination address in the unicast routing
table. If a match is found, the packet is forwarded by way of
the routing table. If no match is found, the packet is forwarded
to the specified next hop.
