hi:Recently, my 6509 bring me a big bad surprise after I enter seven commands “no distributed-list XXX in|out interfaceYYY” at the same time. I mean that I paste the seven commands into the SecureCRT that it has logged in my 6509, and then some routings that do not come from interfaceYYY lost. They do not appear until I type the command “clear ip route * ” and “clear ip eigrp neighbors” at my 6509 after 10mins.
The seven commands applied to my 6509 and topology as follows:
router eigrp 1
no distribute-list denyCFF_host in Vlan811
no distribute-list denyCFF_host in Vlan812
no distribute-list denyCFF_host in GigabitEthernet1/4
no distribute-list denyCFF_host out Port-channel3
no distribute-list denyCFF_host in Port-channel3
no distribute-list denyCFF_forTZHClient out Port-channel5
no distribute-list denyCFF_host in Port-channel5
topology see attachment
I have an idea about routing that come from vlan803, vlan804 disappearing. Whether paste action make this issue? “no distribute-list” can break the connection between neighbors at a moment, and then rebuild their connection and exchange their routing each other. Many “no distribute-list” may be can lead my6509 into computation overhead, or routing table invalidation, so as to portion of routing disappearing.
Can you give me an answer? Or you can tell me the performing process of “no distribute-list” .
Thanks.
