Hallo,
I have a C3560X switch that isn't learning the MAC address of our CPE router. At the moment, we're using C9300 with the same config and it is working (we're changing because the network rack is too small that the C9300 doesn't fit). We've updated C3560x's software to the latest 15.2.7E10 but the problem persists. Below is a snippet of the configs:
hostname SW1
!
!
vrf definition Mgmt-vrf
!
!
address-family ipv4
exit-address-family
!
address-family ipv6
exit-address-family
!
ip routing
!
ip vrf MGMT1
!
interface Vlan898
ip vrf forwarding MGMT1
ip address 10.20.30.5 255.255.255.252
no ip redirects
no ip proxy-arp
!
interface GigabitEthernet0/4
switchport trunk allowed vlan 898
switchport mode trunk
service-policy output WAN-EDGE-4-CLASS
ip dhcp snooping trust
!
ip route vrf MGMT1 0.0.0.0 0.0.0.0 10.20.30.6
And because the MAC address to the gateway (CPE) isn't know, the ping also doesn't work. Thanks.
