FreeRouter as a test environment

A few months ago Kevin Myers of IP Architechs introduced me to a really interesting project called FreeRouter. Being that I absolutely love alternative routing platforms and feature complete simulation environments, this really got me going. I tend to define “feature complete” in a routing platform as something that can do both IS-IS and MPLS. Given that there aren’t many platforms that do both correctly or within a reasonable budget, and offer simulation options, I was pretty excited. I spent a fair amount of time pounding through it. I recommend spending some time with this if you have even remote interest in any of the above technologies. It costs nothing but your time. The project was written and is maintained by a Cisco CCIE and was built (according to his site) as a mechanism to learn. However, the feature list is incredibly complete, and extremely impressive, as seen below:

forwarding: ipv4, ipv6, ipx, mpls, nsh, layer2, irb, atom, eompls, vpls, evpn
routing protocols: ospf, isis, bgp, rip, eigrp, babel, olsr, pim, msdp
lsp support: p2p, p2mp, mp2mp built by ldp, rsvp-te, sr, sr-te, bier
crypto: macsec, ipsec, ikev1, ikev2, tls, dtls, ssh, openvpn
tunnel: gre, ipip, l2tp, pptp, lisp, geneve, nvgre, vxlan, etherip
encapsulation: ethernet, vlan, nsh, ppp, framerelay, pwether, virtppp, hairpin
misc: acl, hqos, nat, pbr, srv6, vrrp, hsrp, transproxy, 6to4, rpl, tunnel, vpdn

My configurations can be found in the Configuration Archive section of this site. It is definitely worth your time to check out.
