Hello all!

I'm from an ITP - Internet Transit Provider, and I'm using an NE40 for a ITP Border Position.

We need to validate the combination between IP-Prefixes, and Origin ASN, to accept and propagate routes, and to verify the source of Blackhole announcements.

I was trying to use huawei eXtended P*** Language, to create the filters similar to Juniper and Cisco IOS-XR.
But i Found some limitations, and I'm not able to migrate from Route-Policy to Route-Filter.

I created an enviroment to simulate and examplify the issue!

- Tests 1 to 5 Works, and comproves that it solud be possible.

 - Test 6, demonstrate a limitation of the maximum conditons of a Clause.

- Test 7 and 8, do not work AND I DON'T KOWN WHY!


I'm using a Call Route-Filter on the cone to do some Traffic Engineering about Black Hole...
And by some UNIDENTIFIED REASON, the router simply does not accept de commit.


Here is a part of the configuration, and later the tests that i made.

Hi,
It seems that your configuration has reached a certain specification limit. Can the commit succeed after deleting several elseif commands? No related document is found. It is recommended that you contact the TAC.The R&D should be familiar with the specifications.

I discovered a way to make it work!
The problem was the parentheses of the matchs...
I'm pretty sure that the cause is some issue on the interpreter of the XPL.
