RIPv2 is easier in terms of configuration, requires no planning and is very often part of the featureset in cheap layer 3 switches. OSPF is more flexible, has a quicker convergence and less overhead. Its a blueprint as well for networks with a single vendor like Cisco or Mikrotik only and also applies to the choice of the dynamic routing protocols. The examples do show setups for Cisco or Mikrotik installations and in the second part includes open source firewalls pfSense and OPNsense. The shown screenshots in this guide can be used for own projects and have to be set to local IP adressing schemes. This also brings native multicast routing and the option to stream audio and video data resources very efficient into remote locations. a quick and automatic backup can be a major pluspoint to mitigate connection problems and keep centralized applications online. a central Voice PBX, cashier systems etc. Especially in remote locations which demand higher avalability due to e.g. With a large number of remote locations also dynamic backup of VPN links can easily be achieved and hence makes the whole network more reliable in terms of possible link or provider faulure. This allows multicast based dynamic routing protocols like RIPv2 or OSPF as well as native multicast Traffic to be carried over secure VPN links.ĭynamic routing protocols ease the routing management and avoid typical config mistakes maked by managing large amounts of static routes in each device. The highlight here is the secure IPsec connection which on top carries a GRE overlay tunnel. It covers a design with a powerful VPN core device in the headquarter location and small remote locations equiped with Mikrotik due to budgetary reasons. It describes a mixed hardware VPN site-to-site setup between Cisco and Mikrotik routers on IPsec basis. The following tutorial is an addon to existing VPN tutorials on.
