DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Enters NTP configuration mode.ntp
Example:
RP/0/RP0/CPU0:router(config)# ntp
Step 2
Specify name of a VRF (VPN- routing and forwarding) instance to configure.
vrf vrf-name
Example:
RP/0/RP0/CPU0:router(config)# ntp
vrf Customer_A
Step 3
Configures an interface from which the IP source address is taken. This allows
IOS-XR to respond to NTP queries on VRF interfaces, in this case the source
is BVI.
source interface-type interface-instance
Example:
RP/0/RP0/CPU0:router(config)# ntp
vrf Customer_A source bvi 70
Step 4
This interface is used for the source address for all packets sent to
all destinations. If a source address is to be used for a specific
association, use the source keyword in the peer or server
command shown in Configuring Poll-Based Associations, on page
147.
