| After it is determined which Route
Processor interfaces will be MLS interfaces, the
interfaces must be added to the same VLAN Trunking Protocol (VTP) domain as the
switch. Both the switch and the MLS interfaces must be in the same
domain. If the switch is not assigned to the VTP domain, this task
does not have to be performed. The configuration in the Figure illustrates
how to assign a VTP domain to an interface.
To place an external Route Processor
interface in the same VTP domain as the switch, enter the following
command in interface configuration mode
Router(config)#interface vlan
vlan_number
Router(config-if)#mls rp vtp-domain domain-name
where domain-name
is the name of the VTP domain in which the switch resides.
Note: For an ISL interface,
enter this command only on the primary interface. All subinterfaces
that are part of the primary interface inherit the VTP domain of the
primary interface.
The running configuration example in
the Figure states that the VLAN41 interface of the MLS-RP is
configured to reside in the cisco
VTP domain. To remove the MLS interface from a VTP domain, enter the
no mls rp vtp-domain domain-name
command.
To view information about a specific
VTP domain, enter the following command in privileged EXEC mode.
Router#show mls rp vtp-domain vtp
domain name
The display resulting from this
command shows a subset of the show
mls rp command display. The
following information is a result of issuing the show
mls rp vtp-domain command.
- The name of the VTP domain(s) in
which the MLS-RP interfaces reside
- Statistical information for each
VTP domain
- The number of management
interfaces defined for the MLS-RP
- The number of VLANs in this domain
configured for MLS
- The ID of each VLAN configured for
this domain MAC address
- The number of MLS-SEs of which the
router or RSM has knowledge of in this domain
- The MAC address of each switch in
this domain
