I have a RB1100AH which means it as two switch
From what I know in order to get the dhcp-server for the other switch I have to bridge two ports from the two different switch
here is the setup
interface ethernet print
Flags: X - disabled, R - running, S - slave
# NAME MTU MAC-ADDRESS ARP MASTER-PORT SWITCH
0 ether12 1500 00:0C:42:EA:66:7C enabled
1 R ether13 1500 00:0C:42:EA:66:7D enabled
2 RS ether1 1500 00:0C:42:EA:66:71 enabled ether3 switch2
3 RS ether2 1500 00:0C:42:EA:66:72 enabled ether3 switch2
4 R ether3 1500 00:0C:42:EA:66:73 enabled none switch2
5 RS ether4 1500 00:0C:42:EA:66:74 enabled ether3 switch2
6 RS ether5 1500 00:0C:42:EA:66:75 enabled ether3 switch2
7 R ether6 1500 00:0C:42:EA:66:76 enabled none switch1
8 RS ether7 1500 00:0C:42:EA:66:77 enabled ether6 switch1
9 S ether8 1500 00:0C:42:EA:66:78 enabled ether6 switch1
10 ether9 1500 00:0C:42:EA:66:79 enabled none switch1
11 ether10 1500 00:0C:42:EA:66:7A enabled none switch1
12 ether11 1500 00:0C:42:EA:66:7B enabled
I add a bridge
> interface bridge print
Flags: X - disabled, R - running
0 R name="bridge1" mtu=1500 l2mtu=1598 arp=enabled mac-address=00:0C:42:EA:66:73
protocol-mode=none priority=0x8000 auto-mac=yes admin-mac=00:00:00:00:00:00
max-message-age=20s forward-delay=15s transmit-hold-count=6 ageing-time=5m
the add the two master port on each switch to the bridge
> interface bridge port print
Flags: X - disabled, I - inactive, D - dynamic
# INTERFACE BRIDGE PRIORITY PATH-COST HORIZON
0 ether3 bridge1 0x80 10 none
1 ether6 bridge1 0x80 10 none
bang no client can get an IP adress anymore !!!
Maybe I’m just tired, but I wonder if one of you have an idea
