Hello everyone
I am facing a issue with our Metro Ethernet switch. I have directly connected a Patton SmartNode 4528 Voip Gateway Router to the Cisco Switch which is the Default Gateway (46.245.137.1). Patton GW every 20 minutes sends an ARP request asking for default gateways mac address. Cisco ME3600X is not responding to Patton ARP request so Patton is losing ip connectivity since is thinking that Default Gateway is down. Routing Protocol is ISIS. I have made the some tests with a Catalyst 2960G which is responding to Patton ARP request. Switch Port configuration interface GigabitEthernet0/23 switchport trunk allowed vlan none switchport mode trunk load-interval 30 service instance 333 ethernet encapsulation untagged service-policy input CORPORATE_IN_10MB service-policy output CORPORATE_OUT_10MB bridge-domain 333 interface Vlan333 bandwidth 10000 ip address 46.245.137.1 255.255.255.248 load-interval 30 #show ip protocols *** IP Routing is NSF aware *** Routing Protocol is "isis" Outgoing update filter list for all interfaces is not set Incoming update filter list for all interfaces is not set Redistributing: static, isis Address Summarization: None Maximum path: 4 Passive Interface(s): Vlan333 Loopback0 Cisco ME3600X is running IOS me360x-universalk9-mz.153-1.S1.bin I have attached 2 wireshark traces one from 3600 and one from 2960.
