VLAN Routing issues

[meziani-tarek25]

Hello I have some trouble with figuring out a solution to make it work for my networkI have a cat 6500 I have interface vlan 60 with network/24 and I need to bind the same network with an other routed physical interface . In short I need to route the same network on the 6500 Switch via two different sources ( interface vlan )and (routed interface , because this one is bundled with an other switch of datacentre via etherchanel and work through encapsulation dot1q and IP address) But I could not give 2 adresses for the previews interfaces from the same network there will be an overlap .Please help me Thank you

Router or SW not accepting two interfaces with same subnet.

Even with using bridge group?

the Bridge group will bridge two L2 interface and the only IP you need is for BVI which represent subnet for both interface.

Have you considered using secondary IP addresses on the Fsginspections interfaces to avoid overlap? Alternatively, subnetting might provide a solution to route the same network via different interfaces.

You cannot assign the same IP subnet to both a VLAN interface and a routed physical interface directly, as this would cause an IP conflict. You could either use different subnets for each interface, or consider advanced solutions like Policy-Based Routing (PBR) or Proxy ARP to manage traffic across the same subnet. Alternatively, you could explore redundancy protocols like HSRP for failover scenario. i also face same issue while working for gouttiere drummondville and i fixed it by using different subnets. if you have already fixed it, share your experience how you tackle it.
