Sorry, can't provide route listing outputs at the moment. I suddenly think
it might be working as I just got the clns routing table from the untrusted
router and there are other NSAPs that I've never seen in my table.
As you can see, this is integrated ISIS. I've left the IP portion in.
This partial configuration is intended to allow a single NSAP through.
clns routing

Subject: CLNS over ISIS
Troy,
ISIS uses filter sets to block addresses. So to block that address you
would enter.
clns filter-set <provide a name> deny 39.800f.4344.8888.0000.0000.00003
clns filter-set <provide a name> permit <provide address>
Do you have the configs for the local and remote routers? If you could
post them we could run the appropriate debugs while testing. Thanks.
