I have a network in which we have enabled MP-BGP , there are multiple VRF configured in network .
Location A we have NTP server with IP 10.1.1.1 in VRF-1 , on Location B we have 7 swicthes out of which 6 access swicthes 4948 I have configured NTP server on all siwtches and its working fine
But the core switch in Location B is not getting sync with NTP server . below is the config which I have put on Core switch
ntp server vrf VRF_1 10.1.1.1
But I can ping the ntp server from the core switch
ping vrf VRF_1 10.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms
Thanks for help

Hi Amit
Try forcing NTP to only use a single interface from the VRF
ntp server vrf VRF_1 10.1.1.1
ntp source
like :-
!
ntp server vrf VRF_1 10.1.1.1
ntp source loopback 1
!

What do you get when you run a debug?
What configuration do you have for your NTP?
What happens if you point your 6500 to NTP synch with your switches?
