HP 2910 - VLAN-routing
Hello all,
got a new HP2910, on which I created 2 vlans for testing:
show ip
IP Routing : Enabled
Default TTL : 64
Arp Age : 20
Domain Suffix :
DNS server :
VLAN | IP Config IP Address Subnet Mask Proxy ARP
-------------------- + ---------- --------------- --------------- ---------
DEFAULT_VLAN | Manual 192.168.7.245 255.255.255.0 No
PCClients | Manual 192.168.1.245 255.255.255.0 No
show config
ip default-gateway 192.168.7.254
ip routing
vlan 1
name "DEFAULT_VLAN"
untagged 1-3,5,7,9-14,18,21,23-24
ip address 192.168.78.245 255.255.255.0
no untagged 4,6,8,15-17,19-20,22
exit
vlan 5
name "PCClients"
untagged 4,6,8,15-17,19-20,22
ip address 192.168.1.245 255.255.255.0
exit
192.168.7.254 is IP from router.
dhcp-relay is activated, but clients from vlan5 do not get an IP!?
From the switch console I can ping clients in both vlans, but between the vlans a ping does not response.
Did I missed anything at the ports configuration?
Are there any options to configure an authorized dhcp-server ip?
thx
P.S. This thread has been moevd from Switches, Hubs, Modems (Legacy ITRC forum) to ProCurve / ProVision-Based. - Hp Forum Moderator

Re: HP 2910 - VLAN-routing
Shouldn't yr VLAN 1 vlan interface be a .7 and not a .78 on the third octet?
I'd prefer to use a static 0.0.0.0 route rather than the "ip default route" when I've got IP routing enabled - buts that's my OCD.

Re: HP 2910 - VLAN-routing
you are right, it is 192.168.7 - was a typing error by myself!
u mean the static 0.0.0.0 route to the router (192.168.7.254) rather than the default route/gateway?
why not use both simultaneously?
---
ok issue is almost cleared.
main problem is a false gateway entry at the dhcp-clients although the dhcp has the correct value.......

Re: HP 2910 - VLAN-routing
If you are not enabling ip routing then you need the default gateway for the switch to communicate with monitoring/management devices outside of the subnet it sits in, but if you are enabling ip routing then adding a 0.0.0.0 route makes more sense as this entry will be used over the "ip default-route" entry. As Ian said, its an OCD thing really, but also it's good house keeping.
Don't forget to mark a post resolved if your question was answered.

Re: HP 2910 - VLAN-routing
default-gateway is disgarded when you have "ip routing" enabled on the switch. You need to set "ip route 0.0.0.0 0.0.0.0 192.168.7.254" as your default route instead.
