Redistribute a new subnet without packet loss

[CoolHandLuke]

Hello everyone,

It's my first post on this forum and my first steps on Alcatel devices.
I would like to redistribute a new route to my other routers.
Here is the simplified configuration on my 6850E Alcatel L3 switch :

Code: Select all

ip access-list "MY-ROUTES"
ip access-list "MY-ROUTES" address 10.10.10.0/24 action permit redist-control all-subnets
ip access-list "MY-ROUTES" address 10.10.20.0/24 action permit redist-control all-subnets
ip access-list "MY-ROUTES" address 10.10.30.0/24 action permit redist-control all-subnets
ip route-map "MY-ROUTEMAP" sequence-number 10 action permit
ip route-map "MY-ROUTEMAP" sequence-number 10 match ip-address "MY-ROUTES"
ip route-map "MY-ROUTEMAP" sequence-number 10 set metric-type external type1
ip redist local into ospf route-map "MY-ROUTEMAP" status enable

How to advertise a fourth subnet (10.10.40.0/24 for example), without interrupting the advertisement of the first three ones ?
It's not possible to edit the access-list, because it is in use.
Should I create a new access-list and add a match command to my routemap ? Will it cause any packet losses ?

Thanks
