Two locations are mainly for carrier uplinks (BGP IPv4/IPv6) and are cross-connected. The third locations is connected to both other locations, doesn’t have to do BGP and serves managed and collocated servers.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Currently we use OSPF for default and internal Ipv4 routes between the locations, which works great and I would prefer to maintain that setup but also apply that for IPv6.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>I’d consider MLX routers for the BGP locations because they would allow larger route tables (or at least in hardware) and more peers.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>For the server location the RX-4 (2 units) should be sufficient only requiring OSPF for no more than about a hundred routes. Now could you guys conform the RX-BI-MR would be sufficient for the RX-4 units, considering I’m not going to do BGP on them?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Another thing I’m struggling with is that I’ve been told that the RX series still push IPv6 through its CPU, causing major performance limitations. I’ve also been told this is not the case with the MLX series. However, I cannot verify this statement anywhere, nor can I track any difference in the datasheet that would implicate there is such difference. Is anyone familiar with this and can tell me whether this is true or a myth?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US> <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:NL'>Kind regards,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:NL'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:NL'>Bardo Cornelissen.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:NL'>Caveo Internet BV<o:p></o:p></span></p></div></body></html>
