снял с платы WS-X6748-GE-TX - DFC и прикрутил на нее CFC, табличка bgp влилась без проблем и ошибок

но тогда модуль работает в режиме

sh fab
show fabric active:
Active fabric card in slot 6
No backup fabric card in the system

show fabric mode:
Global switching mode is Compact
dCEF mode is not enforced for system to operate
Fabric module is not  required for system to operate
Modules are allowed to operate in bus mode
Truncated mode is allowed, due to presence of DFC, CEF720 module

думаю (но пока не уверен) мало памяти на модуле WS-X6748-GE-TX

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/hardware/Module_Installation/Mod_Install_Guide/0adtrcrd.html

 

циска пишет что для WS-F6700-DFC3BXL - 1 GB (и сноска - Requires a memory upgrade on the base module. Refer to the Catalyst 6500 Series DFC3A, DFC3B, DFC3BXL, DFC3C, and DFC3CXL Installation Note for additional information.)

Что-то мне кажется не в количестве памяти тут дело. Маршруты в tcam устанавливаются и с ним какие-то проблемы. Может иос поменять?

Еще циска говорит про такую команду mls cef maximum-routes ... ?

 

Можно еще вывод команды до загрузки full view?

я думаю все-таки дело в памяти

скорее всего он и RIB реплицирует на линейные карты в dCEF режиме

When you upgrade your Ethernet module with either a DFC3BXL or DFC3CXL daughter card, you must also install a 1-GB memory upgrade (part number MEM-XCEF720-1GB) on the Ethernet module. This 1-GB memory upgrade is included with your DFC3BXL or DFC3CXL upgrade kit and installs on the Ethernet module in a small-outline dual-inline memory module (SODIMM) chip socket located underneath the DFC daughter card.

You must perform the memory upgrade procedure after you remove the CFC or the DFC daughter card from the Ethernet module and before you install either the DFC3BXL or DFC3CXL daughter card upgrade.

 

Написано, что память должна идти в комплекте к DFC. Забыли поставить?

Однозначно где-то не хватает памяти, сталкивались с такой же ошибкой на 72хх при попытке залить 3 FV.

А вы случаем не пытаетесь залить фул в VRF (естественно не default) ?

 

Вот это

72 bits (IPv4, MPLS, EoM) 933888 771490 83%

как-то сильно много для fullview...

Ощущение что полученный фул попадает не только в default но и ещё в какой-то VRF.

Количество записей в TCAM длиной 72 бита сейчас примерно 385529 должно быть, а у

вас в 2 раза больше.

из-за vrf-a (mpls) он каждый маршрут складывает в tcam 2 раза

кому интересно решилось вводом команды (ну и конечно же установкой планки памяти 1Г на плату где стоит WS-F6K-PFC3BXL ):

mpls label mode all-vrfs protocol bgp-vpnv4 per-vrf

 

на ios-e:

s72033-adventerprisek9_wan-mz.122-33.SXI5

 

 

таким образом маршруты mpls все метятся 1 меткой

памяти сразу стало много свободной
