Thanks Dave and Tim - looks like multiple lists will have to do.

About as close as I can get to something that actually gives me results is
"interfaces <[ae|ge-1/0/]*> unit <*> family net address <*>" which isn't all
that useful.
It doesn't look like apply-path supports any nesting of regexes either eg:
interfaces <[ae|ge-1/[01]/]*> returns no results at all
Any thoughts?

Re: [j-nsp] apply-path regex for specific interface matching
I'm not sure you can do exactly what you are interested in. I would use two
prefix lists as follows.
policy-options {
prefix-list list1 {
apply-path "interfaces unit <*> family inet address <*>";
}
prefix-list list2 {
apply-path "interfaces unit <*> family inet
address <*>";
}
}

I believe apply-path is a glob, not a regex. A glob is more like a shell wildcard, where "*" matches anything (a regex "*" means "zero or more of the previous part of the match"). I think you'll have to do multiple separate matches and then have multiple entries in your prefix-list. -- Chris Adams ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp

Dredging up an old thread here, but I have a requirement for an apply-path that
matches ae* and ge-1/[01]/[0-4] unit * (for a prefix-list).
I must be missing something fundamental about the regex you can use in
apply-path though, because all combinations I've tried seem to fail.
About as close as I can get to something that actually gives me results is
"interfaces <[ae|ge-1/0/]*> unit <*> family net address <*>" which isn't all

Hi Ben,
I believe this document on the juniper site is what you were looking for.

Subject: [j-nsp] apply-path regex for specific interface matching
Hi all,
I'm trying to generate a prefix-list for all CE-facing interfaces on a PE
(assume L3VPN).
As a test, I'm just trying to match all ge interfaces, but the following
returns no match at all:
prefix-list CE-LINKS {
apply-path "interfaces ge-<*> unit <*> family inet address <*>"; }
I've tried both ge<*>, ge-<*> but no luck either way, and as soon as I remove
"ge-", I get all interface prefixes as expected.
I vaguely remember a post here on this a while back, but I haven't been able to
track it down and google/Juniper docs are not providing any info.
Is anyone aware of 1) a solution, or 2) any docs that go through what regex is
actually available in apply-path?
Thanks,
Ben

I think the ge- part needs to be inside the <>, so try

[j-nsp] apply-path regex for specific interface matching
Hi all,
I'm trying to generate a prefix-list for all CE-facing interfaces on a PE
(assume L3VPN).
As a test, I'm just trying to match all ge interfaces, but the following
returns no match at all:
prefix-list CE-LINKS {
apply-path "interfaces ge-<*> unit <*> family inet address <*>";
}
I've tried both ge<*>, ge-<*> but no luck either way, and as soon as I remove
"ge-", I get all interface prefixes as expected.
I vaguely remember a post here on this a while back, but I haven't been able to
track it down and google/Juniper docs are not providing any info.
Is anyone aware of 1) a solution, or 2) any docs that go through what regex is
actually available in apply-path?
Thanks,
Ben
