I created configuration there are two separate firewalls (gateways) one for the workstations networks(L3 VLANs)and one for the servers networks (L3 VLANs). Workstations and servers must communicate with each other.
Workstations must get their ip addresses from DHCP server. For that reason i created to VRF routers "toonet" and "servnet", configured the VRF routers interfaces and default gateways. I used BGP to make inter VRF routable. All went well BGP routing etc. Even workstation got their ip addresses from DHCP server.
From the Cisco 3750-E side all looked correct but then I tried to ping from one workstations to an other workstations (notebooks) and servers then ping request timed out 135 seconds and after that ping worked normally 45 seconds and then ping request timed out 135 seconds etc.
This kind of strange ping behavior continius for ever. But then I repeared or disabled/enabled workstation the network connection under MS Windows XP then the ping continued normally.
There are some other strange things :
then I can not ping others hosts I can ping VLAN IP addresses;
then I added into 3750-E configuration workstation static arp entry into workstation vrf then the ping worked normally (arp vrf toonet "workstaion ip aaddress" "workstation mac address" arpr );
then I tried to ping server from an another server all is working well.
Can any one help to solve this problem of my configuration and make it work.
I added my configuration file and picturs of my hardware and VRF setup as attacment.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
