We have a central location (can be called as HUB location) to which multiple branch locations connect over MPLS connectivity. Currenlty we are using non-Cisco device to terminate MPLS links in central location. CE-PE routing protocol used is BGP.
Since there are multiple MPLS service providers are involved and each of them use different AS numbers, we made use of virtual routing instances to use multiple BGP instances.
In future, we are planning to buy Cisco routers to terminate these MPLS links. As per our findings, Cisco ISR 4451-X suffice our requirement in terms of bandwidth, number of sessions etc...
However, we are not able to find any document as such, which gives information of multiple BGP instances configuration or virtual router instance configuration.
So, we would like to know whether Cisco 4451-X ISR supports multiple BGP instances?
Also it would be helpful if anyone can help to know whether is there any possibility to cluster 4451-X routers or any other way to build redundancy in terms of hardware.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
