Typically in this scenario I would recommend one of two things:
1) Use an MPLS VLL/L2-psuedowire with a secondary failover endpoint on one
side.
Only some equipment vendors implement this (Juniper being one of them)
2) Use a PPPoE pado delay. Set one BRAS to be some decent amount
I assume you're using MikroTik.
You can run multiple PPPoE servers on a single Ethernet segment. The client
will send its PPPoE Active Discovery Initiation (PADI) packet, and both servers
will reply with their PPPoE Active Discovery Offer (PADO). The client will then
select which AC it wants
Our MikroTik BGP router keeps crashing about once every month or
so...sometimes sooner, sometimes later. We are using full BGP tables
and 4.11 currently.
Heard on Mikrotik forums 4.10 is more stable for BGP. When it crashes
are there warning signs like high memory or CPU usage?
We had problems with 4.10 and went back to 4.3 and all is well.
Haven't had a reason to upgrade to 4.11 but we'll probably just move
straight to 5.0.

The higher end routers do their work in hardware with specific
processors and memory for each function, which allows things like
redundancy, speed, and hot-swap capabilities. I can pull any card from

Hardware redundancy, wire speed packet forwarding, support for more Interface

I'll use a MikroTik, Linux, or BSD box as an aggregation router any day;
terminate some VLANs, act as an MPLS CE, perform QoS marking, and participate
in an OSPF area.

I think one of the main differences is BGP failover. With one box,
your BGP session never drops. With two distinct servers, the session
will drop and the second router will start it up. Then, when the
primary comes back online, the session will drop again and restart.
Having two routers talking to each other is not the same as a single
router with redundant parts. I can pull the CPU card from my Cisco and
the box never misses a single packet because the 2nd CPU card is in the
same box. Same with the route processor cards. Same with the power supplies.

You also have the problem where you cant have 1 ethernet cable plugged into
two routers at the same time, unless you add switches in the front, which
then adds complexity to setup and another point of failure. There is no
question that there is value to a hardware redundant single server, in a

Hot Swap is hard to fully accomplish with PCs. Everyone needs a plan for how
maintenance will occur with minimal downtime.
For example, its prettty easy to buy a nice Rack case with redundant PS, but
how do you replace an overheating CPU?
