Hi Group,
I want to know when the table-map command should be used?
The document said it is to set the tag and route metric.
I have tried to set the route metric with the command and the route-map
method. The difference is only in the metric value in the bgp routing table.
With table-map, it is not changed but metric is changed with the route-map.
So, what is the function of the table-map? How to use it?
TABLE-MAP
router bgp 34
table-map tag
neighbor 172.16.13.1 remote-as 100
route-map tag permit 10
match ip address 22
set metric 10034
!
route-map tag permit 20
