After the FRRouting project forked quagga, back then quagga was the most advanced dynamic routing software suite available at the time for linux. There is also BIRD internet routing daemon, it is used at many european IX's mostly due to its stable BGP implementation. BIRD supports most important routing protocols. After the FRRouting project released the 6 major versions of its software, version 7.5 of frr is appeared in portage, Result of an eix search on a gentoo system:
These are the packages that would be merged, in order:

FRR project continues the previous work of Quagga. FRR supports a big amount of dynamic routing protocols that have not been there before, some exotic and interesting examples:
At the beginning of 2018 Clarence Filsfils talked about the implementation status of segment routing and reported that he and his team project participants received huge support from the networking community. The segment routing implementation in FRRouting is still in an early phase. Additionally it is implemented for both routing protocols OSPF and in IS-IS at same time. The SRv6 arrived already in current used stable linux kernels versions, there was a lack of a control plane for the Segment Routing Protocol. FRRouting now fills the gap. Here is an nice overview of the current RFC compliance in its implementation.
FRRouting is a powerful dynamic routing protocol package for linux. Check out some netlab using FRRouting software, Try to build own suckless FRRouting GNS3 guest using alpine linux. You will not find this appliance the GNS marketplace.
