Replacing Cisco 3750 with Procurve 2900
I have a core switch Cisco 3750, with two connections to a Cisco PIX Firewall
and a VPN router which then connects to 2 external VPN Router installed sites.
I want to replace the Cisco, so I recently Installed a new procurve 2900 core switch, which I
could connect to the internet and into our DMZ both of which go through the firewall so I’ve got those
routes right but I couldn’t ping the BT VPN routers at both of the other sites?
Is it because, currently, one of the ports on the Cisco 3750 core has an IP address
assigned to it which is the IP address of the BT VPN router but the Procurve switch doesn't
have an IP address?
Also I was unable to assign an IP address to the DEFAULT_VLAN.
The Cisco 3750 doesn’t have an IP address on VLAN 1 but, as far as I can gather, you have
to assign one to DEFAULT_VLAN on the Procurve switch if you want the web browser to work.
I tried to configure an IP address on VLAN 5 to be the same as the Cisco 3750
it kept saying inconsistent value and the only way to get around it was to give it a
subnet of 255.255.255.252 instead of 255.255.255.0.

Another issue I am having is that on the cisco 3750, I had an ip address of 192.168.5.2 255.255.255.252 connected to our external VPN site, how do I configure this same setup on an interface on the Procurve 2910? so i can ping these remote sites? as far as I know, IP addresses can only be assigned to vlans and not specific ports? Would I have to enter a route?
