hardware/software: l3 vlan routing on X670G2 ver15.6.3.2 patch1-8
when MAC/IP address is moved from port to port, sometimes the arp table updates slowly causing connectivity problems with other vlans. L2 connectivity seems fine.
Is there a way to force updates to the arp table immediately when a mac changes in fdb?
Was wondering if configure ip-arp fast-convergence would help.
on force10 I use mac-address-table station-move refresh-arp
anything similar. I'm still pretty new to xos
thanks

Mark,
The iparp fast-convergence feature maintains the IPARP entry in the event of an FDB flush. So you would essentially see an ARP entry in the table without a port associated until the FDB entry is relearned. It is intended for improved convergence times for ring topologies (EAPS), but could be beneficial in other scenarios as well.
