Re: RPKI

Thank you very much for this information. Any idea when ROS 7 will be available for testing? I'm willing to test RPKI for you (IPv6 and IPv4 routes) if you send me the code as soon as it's available ;)

Cheers, Jan Zorz

Re: RPKI

I'm eagerly waiting for Mikrotik to deploy RPKI route origin validation. Currently I'm doing it on ASR1k router but would gladly move this function to CCR1036 as it seems to be powerfull enough to take care of this stuff. Mikrotik staff, any information when can we expect RPKI in RouterOS? Cheers, J...

Re: RP Filter Loose Reverse Path Forwarding Ignoring Default

Completely agree, this would be preferred and in accordance to BCP84 - http://tools.ietf.org/html/bcp84.

Feature request: BGP additional path propagation

Hi, This feature is very useful for many things, read the document below. Cisco implemented it and many operators is using it. http://www.cisco.com/en/US/docs/ios-xml/ios/iproute_bgp/configuration/xe-3s/irg-additional-paths.html Can we hope to have it in at least ROS7? Cheers and thnx, Jan Zorz

Re: multihoming and source address of outgoing icmp messages

you have to mark packets from up-stream and then add routing-mark to them ensuring that the router will answer on the same interface it received packet from. But I should do this only for icmp packets, directed to the router itself (input chain). I'm not interested in touching any other traffic, BG...

Re: multihoming and source address of outgoing icmp messages

I would think that the natural IP to respond would be the IP that received the request. Well, yes, indeed. But I have 3 different uplinks to 3 different ASN-s and when you do a traceroute from outside towards my network and match the hops to ASNs, then sometimes it happens that return path is diffe...

Re: multihoming and source address of outgoing icmp messages

You can use src NAT on ICMP to change the originating ip. You'll probably want to match the src addresses on the rule so as to not to match ICMP passing through the router. This is an ugly hack, I have to admit :S If there are no other options that I'll have to use it, but probably it would be a ve...

multihoming and source address of outgoing icmp messages...

Hi, I've been trying to figure out this for some time now. I moved all 3 uplinks from Cisco box to CCR and everything works fine - except that RouterOS seems to select out-interface address as a source address for packets originating for the router itself - in this case icmp messages used for tracer...

Re: PPPoE & IPv6

How about the /48 IPv6 PI assignments - with ~200 customers in a rural area I'm still a bit too small to become a LIR (for cost reasons), so can't get a /32 but only a /48 IPv6 PI (currently have /23 IPv4 PI for BGP with two uplinks, and just starting to look into IPv6) - is there a chance to propo...

Re: PPPoE & IPv6

I would think that /64 for residential and /48 for business would be fine. Not sure why home users would need to subnet? Dude. V6 is introduced to give everyone enough addresses. There are enough addresses available and no reason to conserve. It's not difficult to imagine that users would like one ...

Re: PPPoE & IPv6

you do not need addresses for intermediate network stuff, just the end equipment of users should get the address. There you give out addresses with /64 Anyway, nothing that script cannot do. We actually put global IPv6 addresses on eth interfaces, just for later troubleshooting purposes. Problem is...

Re: PPPoE & IPv6

if client is receiving /64 prefix, you could get the value and assign this address using script :) as there is not yet a testing-build available with this feature automated in dhcp-client. No way, /64 PD is a very wrong thing to do for ISP. They do /56 for residential user and /48 for business - as...

Re: PPPoE & IPv6

assignment of acquired address on one of the interfaces with /64 and advertise is coming. Can you predict when? We are testing IPv6 over pppoe for our ISP and having DHCPv6 client with PD is great, but we need PD assignment to interfaces in order to render your device useful :) If there is any ROS ...

Re: PPPoE & IPv6

Hi, in ROS 5.9 we have DHCPv6 client, that is able to receive PD. Fine, great job, we were all waiting for that. What I'm missing is the configuration option to which ethernet port(s) we automatically provision first (and consequent) /64 subnets. On Linux you have this option in dhcp6c config: confi...
