Communities are usually applied to prefixes via route-maps. In your example, RouterA may have something like this: route-map to-router-b permit 10 description Tag Prefixes with Community match ip address prefix-list my-prefixes set community 65530:1234 additive The above will add an additional BGP community to the prefix on egress to RouterB (presuming ...

If all of the /26 networks are hosted on the same device, yes you can summarize with a single /24 route on your edge device. For example, if all of the /26 networks are on a switch at 192.168.254.254 and you have a valid path from the router to the switch on that network, you could use a route on your edge router such as: 10.0.0.0 255.255.255.0 192.168.254....

The "incoming fiber connection" needs to be something you can get an SFP module for, e.g. 1000BASE-LX(10) or 1000BASE-BX10 - check with your ISP what type is required. Connecting GPON (1000BASE-PX10-D) directly to a 2530 is not possible. Also, check your contract where the demarkation port is. If it's the copper port on the "modem" you ...

Router on a Stick refers to a router that's just using a single physical interface. That can be a reasonable setup when multiple VLANs are trunked to that interface (to multiple logical, virtual interfaces), using the router for inter-VLAN routing. If you route between multiple physical interfaces that's no RoaS, just routing without physical-layer ...

A router's routing table is independent of the routing protocol, e.g. RIP, database. The routing table will have the next hop address. RIP stores the next hop in its database as the address of the router from which it received an advertisement. If that route is selected as the best route for the routing table, then the routing table will use that address as ...

You are missing VLANs on your switches. For example, switch 1 is missing VLANs 10 and 30. The others are missing VLANs as well. You can add then using the global command Vlan 10 Name abc
