Hi all
I'm doing a very basic self contained test here where I have a CRS309 running v7.1 and a single laptop connected to a port. I then created a new VLAN, e.g. 53 using the default bridge as Interface, and then created an SVI equivalent, e.g. 192.168.53.1. I then set the interface the laptop is connected to using the default bridge, even untagged vlan 53 though according to the documentation that is unnecessary if the PVID is already set to that vlan. Either way, my laptop has an IP of 192.168.53.11 so same /24 and all works well. I can ping the laptop from the SVI no problem. I can create a new SVI on another vlan on the same bridge and no issues pinging.
[user@crs309test] /interface/bridge/vlan> /ping 192.168.53.11 src-address=192.168.53.1
SEQ HOST SIZE TTL TIME STATUS
0 192.168.53.11 56 64 665us
1 192.168.53.11 56 64 685us
The problem comes when I make a new bridge, because I want to leave the default bridge as is and make my changes on a new one. I created a new bridge (Custom1), moved the VLAN interface over, the physical interface where the laptop is connected to, as well as where you untag your vlans in. Pings stop working. When I check the arp table, I can clearly see ARP is a problem
[user@crs309test] /ip/arp> print
Flags: D, P - PUBLISHED; C - COMPLETE
Columns: ADDRESS, MAC-ADDRESS, INTERFACE
# ADDRESS MAC-ADDRESS INTERFACE
3 D 192.168.53.11 Custom1
[user@crs309test] /interface/bridge/vlan> /ping 192.168.53.11 src-address=192.168.53.1
SEQ HOST SIZE TTL TIME STATUS
0 192.168.53.11 timeout
1 192.168.53.11 timeout
I switch it all back to default bridge, arp works again and the switch can associate IP with mac, and all is good. Just to reiterate these are just tests from the same switch. Any ideas??
