to see it like that ^ from configuration mode use show | display set

commiting configuration to apply it at right time and avoid late night drive to work (candidate configuration, rollback, commit confirmed, ...)

junoscript, junos automation to make network management easier

juniper ex8200 and bgp full table, :-( [j-nsp] TCAM full on EX8200?

I created three scenarios for customer. One of that was ex8208 with acting also like bgp full view router. But after reading this I am going to consider it
http://www.gossamer-threads.com/lists/nsp/juniper/31959?nohighlight=1#31959
Ex8208 has may have some problem with full routing table. :-(

[j-nsp] JUNOS and 128.0.0.0 martian (JFYI), IANA

INANA allocated new addresses. These are martians for Juniper.
for example
https://apps.db.ripe.net/whois/lookup/ripe/inetnum/128.0.0.0-128.0.7.255.html
Take a look at RFC5735 which obsoletes RFC3330.


So if you have it as martians, you possibly cannot route to that remote subnets. Also transit ISPs should change this if they dont route them.

Couple updates about it.

martians are per table in Junos, so if you run internet in vrf (yes,
there are such people!) you need to use that command per routing instance.

RIPE NCC was awared about this issue and now reallocate blocks to those
who got addrs from 128.0.0.0/16

IANA changed it. there was mail.ru now there is nothing
