Aggregate interface with VLANs
Dear community,
I need your help,
I created an aggregate interface (Port1 and port2) with multiple VLANs for internal network, there is no ip address on aggregate interface
when connected those ports (Port1 and port2) to a cisco switch (Interface g1/0/1 and g1/0/2) the link doesn't come up, so the fortiGate can't communicate with the internal network (Cisco switch)
On Cisco switch :
- interface g1/0/1 :
switchport trunk native vlan 99
switchport mode trunk
end
- interface g1/0/2 :
Switchport mode trunk
end
Interface vlan 99 : 192.168.254.251/29
ip route 0.0.0.0 0.0.0.0 192.168.254.254
On fortigate (Aggregate interface) i have multiple VLANs, vlan 1, vlan 100, vlan 110, vlan99 ...etc,
- Sub-interface of VLAN 99 : 192.168.254.254/29
Any help please,
Thanks
