Router(config)# interface interface number

 

Router(config-if)# mls rp vtp-domain domain-name

 

45. View information about the specified VTP domain :

 

Router# show mls rp vtp-domain vtp domain name

 

46. To determine the RSM or management interface on the router, the following command can be entered at the interface mode:

 

Router(config-if)#mls rp management-interface

 

47. To verify the configuration of the MLS-RP :

48. Verify the MLS configuration on a specific interface :

 

Router# show mls rp interface interface number

 

49. In order to set the flow mask on the MLS-SE and do not want to set the access list on any of the route processor interfaces:
