The sum of all classification fields requested in ipv6Pol is 136, which is greater than
128-bit CAM entry size limit. Although this configuration fails to attach to the interface
in JunosE releases earlier than Release 10.2.0, it is successfully attached to the
interface, beginning with JunosE Release 10.2.x, and the next higher 288-bit CAM entry
is allocated for this policy (two 288-bit entries because of two classifiers being defined
in the policy).
In this example, a policy with a combination of IPv6 classifiers is created and attached.
Match all TCP packets from host 1:1:1:1:1:1:1:1 to host 100::1 destined to port 80 from
1.
source port 10000
host1(config)#ipv6 classifier-list tcpCLACL source-host 1:1:1:1:1:1:1:1 destination-host
100::1 tcp source-port eq 10000 destination-port eq 80
Match all frames with the color red
2.
host1(config)#ipv6 classifier-list colorCLACL color red
Create an IPv6 policy list.
3.
host1(config)#ipv6 policy-list ipv6Pol
host1(config-policy-list)#classifier-group tcpCLACL
host1(config-policy-list-classifier-group)#forward
host1(config-policy-list-classifier-group)#classifier-group colorCLACL
host1(config-policy-list-classifier-group)#forward
host1(config-policy-list-classifier-group)#classifier-group *
host1(config-policy-list-classifier-group)#filter
The policy ipv6Pol is requesting classification on Source Address (all 4 words),
Destination address (all 4 words) and Protocol. Table 27 on page 165 lists the active
classifiers in the policy named ipv6Pol and the size of each classifier.
