Hi
I'm rather new with cisco still, we have a catalyst 2960 that sit in front of our 2 Sophos Firewall in active/passive mode.
Currently our internet provider arrive on port 1 and the data is split into the 2 10g port each going to a firewall creating a lag (configured to use vlan96).I didn't do this, configuration look like this :
vlan internal allocation policy ascending
!
vlan 74
name VL-193-63-109-72-JN
!
vlan 96
name VL-194-195-187-JN
interface GigabitEthernet1/0/1
description ### Uplink to JANET ###
switchport access vlan 74
switchport mode access
interface TenGigabitEthernet1/0/1
description ### Uplink to FW-UTM-1 C2 ###
switchport mode trunk
channel-group 1 mode active
!
interface TenGigabitEthernet1/0/2
description ### Uplink to FW-UTM-2 C2 ###
switchport mode trunk
channel-group 1 mode active
!
interface Vlan1
no ip address
!
interface Vlan74
ip address 193.63.109.74 255.255.255.252
!
interface Vlan96
ip address 195.194.187.126 255.255.255.224
ip default-gateway 193.63.109.74
no ip http server
no ip http secure-server
!
ip route 0.0.0.0 0.0.0.0 193.63.109.73
I have to migrate our connection and as of now i have managed to make it work but only connecting directly to a single firewall, which is not ideal.
We want to use this device in order to split the traffice for the new provider (EE) and all their traffic split between 47/48
our provider gave us 5.148.134.68/31, ip in 69 routing to 68, and a public range of 5.148.143.240/28.
I was going to configure the "in" like this :
vlan 69
name VL-5-148-134-69-EE
interface GigabitEthernet1/0/2
description ### Uplink to EE ###
switchport access vlan 69
switchport mode access
interface Vlan69
ip address 5.148.134.69 255.255.255.254
but for the connection to firewall can i do the same with trunk channel group(lag configured on the other side with different vlan, possibly 240) and having to "sacrifice" one of our public ip ?
It would seems more logical for me to have Tg1/2 being configured as access vlan 96, and 47/48 as access vlan 240.
should i remove the default-gateway and add a route for 5.148.134.68 or should i simply let the vlan speak and do the routing ?
Thanks for the help
