Creating Classifier Control Lists ! 17

Chapter 2: Creating Policies

! local true—Matches packets that are destined to a local interface.

! local false—Matches packets that are traversing the router; this is the

default setting.

For example:

host1(config)#ipv6 classifier-list svale20 source-route-class 1

host1(config)#ipv6 classifier-list svale30 destination-route-class 1 tcfield 10

host1(config)#ipv6 classifier-list svale40 source-route-class 1 local true

host1(config)#ipv6 classifier-list west25 source-route-class 1 local false

In the previous example, classifier control lists match route-class values as

follows:

! svale20 matches the source address lookup route-class value of 1.

! svale30 matches the destination address lookup route-class value of 1 and

a traffic-class value of 10.

! svale40 matches the source address lookup route-class value of 1 and the

packets destined to the local interface.

! west25 matches the source address lookup route-class value of 1 and

packets that are not destined for the local interface (packets destined for

remote interfaces).

! Use the source-address, source-host, destination-address, and

destination-host options to classify traffic based on source and destination

addresses. You can specify the address as an IPv6 address or an IPv6 prefix. In

the following example, traffic is classified on source host address

2001:db8:1::8001 and destination address 2001:db8:3::/48:

host1(config)#ipv6 classifier-list YourClaclList source-host 2001:db8:1::8001

destination-address 2001:db8:3::/48

! Use the following keywords to specify traffic class information in the IPv6

header:

! tcfield—Specifies the use of the whole 8 bits of the traffic-class byte; range

is 0–255

! dsfield—Specifies the use of the upper 6 bits of the traffic-class byte; range

is 0–63

! precedence—Specifies the use of the upper 3 bits of the traffic-class byte;

range is 0–7

! Example

host1(config)#ipv6 classifier-list ipv6classifier color red user-packet-class 5

tcfield 10

! Use the no version to remove the classifier control list.
