Configure Allowed Networks
Configure network addresses to determine the network addresses that BGP advertises. The allowed addresses determine the BGP networks that originate from the switch.
Before you begin
You configure BGP on a VRF instance the same way you configure the GlobalRouter, except that you must use VRF Router Configuration mode and the prefix ip bgp. The VRF must have an RP Trigger of BGP.
Procedure
Example
Specify IGP network prefixes for BGP to advertise:
Switch(router-bgp)# network 2001:DB8::/32 metric 32
Variable Definitions
The following table defines parameters for the network command.
Variable |
Value |
---|---|
WORD <1–256> |
Specifies an IP address and its length in the appropriate form. |
metric <0-65535> |
Specifies the metric to use when the system sends an update for the routes in the network table. The metric configures the MED for the routes advertised to eBGP peers. The range is 0–65535. |
