Jul 17th, 2010

Hello,

My companny just purchase cisco 6500 with IOS slb and 8 7206 vxr to inmlement a DMVPN cloud.

I finished all configuration and i am experiencing a small problem with the behavior of the slb.

I configured two vserver on the 6500 and the 8 7206 in configured as the FARM for the IPSEC & GRE.

ip slb vserver ESP
virtual 10.160.0.14 esp
serverfarm 7206-FARM-DRP
sticky 3650 group 1
idle 3660
inservice
!
ip slb vserver ISAKMP
virtual 10.160.0.14 udp isakmp
serverfarm 7206-FARM-DRP
sticky 3650 group 1
idle 3660
inservice

It all work fine but after a while the slb conn table show two or more conn that open to the ESP vserver

CLALIT-HUB-3-DRP#sh ip slb connections  | i 1.8.59.254
ESP             ESP  1.8.59.254:1633       10.151.0.7            ESTAB     none
ISAKMP          UDP  1.8.59.254:500        10.151.0.7            ESTAB     none
ESP             ESP  1.8.59.254:52224      10.151.0.7            ESTAB     none
ESP             ESP  1.8.59.254:20622      10.151.0.7            ESTAB     none

Is this behavior is normal ?

See the attached configuration of my 6500 & one of my 7206 farm router
