Hello, I built a int vlan with a vrf domain and a HSRP with a virtual gateway. The core switch is configured with DHCP server. Once the lap top gets its ip from the  server. I'm unable to ping the HSRP gateway. Can anyone assist with this on.

ex.
ip dhcp-excluded 1.1.1.1 - 1.1.1.2

ip dhcp pool_200
network 1.1.1.0 255.255.255.0
default-gateway 1.1.1.1

int vlan 200
description test1
ip vrf forwarding webaccess
ip address 1.1.1.2 255.255.255.0
 standby 1 ip 1.1.1.1
 standby 1 timers 1 3
 standby 1 priority 110
 standby 1 preempt


Laptop grabs 1.1.1.5, but I'm unable to ping the gateway?

According to the RFC for VRRP a router should not respond to ping to the VIP.
Perhaps you have the same here?

Can you ping .2?

Please paste the full config. What is the use of vrf here? where is the vrf config? What are you trying to achieve by putting vrf in a single switch?

The use of the VRF on this vlan is to isolate it's traffic. The workstations receives it's ip from the DHCP server from the switch.

Once the workstation receives it's ip. I'm unable to ping vlan(HSRP) gateway from the workstation. I believe the DHCP needs to be in the vrf for me to ping it...Please advise


Here's the initial config.



ex: initial config:

ip dhcp pool_200
network 1.1.1.0 255.255.255.0
default-gateway 1.1.1.1

int vlan 200
description test1
ip vrf forwarding webaccess
ip address 1.1.1.2 255.255.255.0
 standby 1 ip 1.1.1.1
 standby 1 timers 1 3
 standby 1 priority 110
 standby 1 preempt



Workaround config:

ip dhcp use vrf connected

ip dhcp pool_200
vrf  webacces
network 1.1.1.0 255.255.255.0
default-gateway 1.1.1.1

int vlan 200
description test1
ip vrf forwarding webaccess
ip address 1.1.1.2 255.255.255.0
 standby 1 ip 1.1.1.1
 standby 1 timers 1 3
 standby 1 priority 110
 standby 1 preempt

ip vrf webaccess

interface FastEthernet0
ip vrf forwarding webaccess
ip address 1.1.1.2 255.255.255.0

no ip dhcp use vrf connected

ip dhcp excluded-address 1.1.1.1 - 1.1.1.2


ip dhcp pool pool_200
   network 1.1.1.0 255.255.255.0

   default-router 1.1.1.2

The above one works. However it's not what you are looking for with respect to dhcp. I will try use the vlan and hsrp shortly.

Best,

Ok, I did not have any switch in my possession. So here is what I did trying to replicate the closest possible scenario. I took a router-->configured it as dhcp server/VRF/HSRP. Took another router as a DHCP client(instead of laptop) and was pinging the HSRP IP of 1.1.1.100 in the dhcp server. Attaching the 2 configuration files.
Client router (consider laptop) can successfully ping the HSRP IP.
Hopefully the author can replicate the solution now.
