[c-nsp] NHRP and DMVPN problems

[Jason Koh]

Hi all

Wonder if any of you uses nhrp tunnels in your 7206s. 

A sample of the config

interface Tunnel1
 bandwidth 1000
 ip address 10.10.10.1 255.255.255.128
 no ip redirects
 ip mtu 1514
 ip nhrp authentication dmvpn1
 ip nhrp map multicast dynamic
 ip nhrp network-id 1
 ip nhrp holdtime 300
 no ip mroute-cache
 tunnel source Loopback1
 tunnel mode gre multipoint
 tunnel key 1
 tunnel protection ipsec profile dmvpnprof1

crypto ipsec profile dmvpnprof1
 set security-association lifetime seconds 120
 set transform-set dmvpnset1 

crypto ipsec transform-set dmvpnset1 ah-sha-hmac

Currently I am running IOS 12.3(14)T5, c7200-jk9s-mz.123-14.T5.bin. This router keeps rebooting occasionally with software crashes.

System returned to ROM by error - a Software forced crash, PC 0x60801E58 at 08:03:12 SGT Fri Oct 6 2006
System restarted at 08:08:57 SGT Fri Oct 6 2006

Wonder anyone out there encountered such a problem and would appreciate if you can share your findings as well.

Thanks
