By default, ZXR10 interprets the parameter <prefix-access-list>
after the keyword for according to the rule described in the in-
struction of the mpls ldp advertise-labels command.
Generally, the parameter <prefix-access-list> after the keyword
for conforms to the following rules:
One (prefix acl, peer acl) pair "applies to" a prefix only when the
prefix ACL "matches" the prefix, and the match condition is that
the prefix ACL permits the prefix. This is the general processing
method of access list.
In the early Cisco IOS version, however, the parameter <prefix-ac
cess-list> after the keyword for in the mpls ldp advertise-labels
command is interpreted in a different way as follows:
One (prefix acl, peer acl) pair "applies to" a prefix only when the
prefix ACL "matches" the prefix, and the match condition is that
prefix ACL permits or denies the prefix explicitly. The parameter
prefix ACL with "permit any" or "deny any" matches all prefixes.
The difference between the Cisco early rules and the general pro-
cessing method of access list is that:
The explicit deny (including deny any) makes the (prefix acl, peer
acl) pair "applied to" the prefix, while the implicit deny does not
take any effect.
If users are used to the early rule, the mpls ldp advertise-labels
old-style command can be used.
This example describes how to configure the router to use the early
rules of Cisco to interpret the parameter <prefix-access-list> after
the keyword for in the mpls ldp advertise-labels command.
