VLAN Ethernet: When to use?

IngoPohlschneider
Hello
I support a ASG 425 that is currently configured with several VLANs on the lag0 interface.

I wonder if this is required...

1) There is a coreswitch that does the routing between this VLANs anyway (so ASG is not involved in any filtering between VLANs...I guess that would be a usecase for using VLAN-interfaces in the ASG?)

2) The core switch has a default route set to one of those IPs of the ASG

Wouldn't it be smarter / less cluttered to configure just one standard Ethernet Interface with that IP address and kick out all the other VLAN-Interfaces?

Best regards and sorry for the pretty basic question

    Hello
    I checked more closely for dependencies and routing settings. now got rid of the unneeded interfaces without any issues.

    I don't agree on that since there are currently no internal restrictions between networks. Therefore using the VLAN-Interfaces would only generate additional load on the ASG w/o any other benefits. 

    Best regards
