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....
This is possible. There is a feature called additional-paths advertise|install which is an enhancement to the BGP protocol, but it must be supported by both parties. Also check the BGP PIC feature.

A Cisco router can install multiple paths into the RIB using the maximum-paths command. This will allow the router to 'load share' among the paths.
However, the router will only advertise the best path to its peers, regardless of how many paths are in the RIB.
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 ...
