IPv6 access-class vs IPv6 traffic-filter

These commands appear to be interchangeable.

Is one preferable to the other?

If so, under what circumstances would one choose one over the other?

Re: IPv6 access-class vs IPv6 traffic-filter

Hi Manuel,

The difference depends on whether you want to filter IPv6 traffic sent *to* the router or *through* the router.

The 'ipv6 traffic-filter' command is used to filter IPv6 traffic flowing through an interface:

Command reference (with example):

The 'ipv6 access-class' command is used to filter IPv6 traffic destined to the router (i.e. management traffic).

Command reference (with example):

Hope that helps.
