Hi all,

all my configuration is on the vrf-default.

i'm trying to ping in my core switch his interface but i have response "Packet transmit error; Destination unreachable"

there is my config!

create vlan VLAN2
config vlan VLAN2 tag 2
config vlan VLAN2 add ports 1:1-4 tagged
config vlan VLAN2 ipaddress 10.254.1.254/24
enable ipforwarding VLAN2
create vlan VLAN3
config vlan VLAN3 tag 3
config vlan VLAN3 add ports 1:1-4 tagged
config vlan VLAN3 ipaddress 10.254.3.254/23
enable ipforwarding VLAN3
create vlan VLAN6
config vlan VLAN6 tag 6
config vlan VLAN6 add ports 1:2-4 tagged
config vlan VLAN6 ipaddress 10.170.1.250/22
enable ipforwarding VLAN6

in my opinion it's not ok! for example, when we have another dhcp server on VOICE vlan, how we do?
how the client join his correct server?

thank's every body, it semms ok now.

i juste reconfigure my core and i reload it!

so i have another question about dhcp relay, i want to activate a dhcp relay on vlan data.

i configure the ip adresse of my dhcp server on vr-default then i just enable bootprelay on the vlan?

there is my conf:

configure bootprelay add 10.170.10.30 vr VR-Default
configure bootprelay add 10.170.10.31 vr VR-Default
enable bootprelay ipv4 vlan DATA

thank's for your help

Hi,

possible issues:

- you're on a different VR: you say that everything is on VR-Default, so I assume this is not the case. However you do say also "result of my ping in management vlan". The out of band management interface is in a different VR. So if you try to reach your vlan from the management vlan, that's the issue, assuming you didn't ping from the box itself (which defaults to VR-Default).

- the VLAN aren't Up: so that a VLAN is Up, you need at least one port Up in that vlan. A "sh vlan" would help to troubleshoot. You can create a loopback interface per vlan if needed.

if not that, as Parthiban said, try to re-enable ipforwarding.

enable ipforwarding one more time.
I guess internal TTL is changed.
See if you can reboot for temporary workaround.
Let me know if this solves your issue.
there is a known issue.
