Hello everybody ! I have one Mikrotik CCR1009 which is configured as main router and a CRS125G which is connected to the CCR in bridge mode. On the CCR I have configured everything that I need e.g. all interfaces,vlans and a bridge to which the CRS is actually connected. Everything works fine except that I can't ping addresses in different subnets. I have searched the forum but couldn't find anything that can actually help me resolve my issue. I will be very pleased if someone can help me. If necessary I can do an export of the current configuration.

An export would help. Its either a routing issue or a firewall rule blocking it.

Here is the export from Route and Firewall sections:

/ip route
