Hi Ibrahim,   1- A label should be allocated by both SR and LDP.   2- LDP is preferred by default. You can use "sr-prefer" command to change this default behavior.   Regards, ... View more

That is correct. NAT64 is pretty much the only way to provide communication between IPv6 only and IPv4 only devices.   Regards, ... View more

I see you do not have your own router. Is your provider publishing the prefix you received from LACNIC via BGP? If so, they should configure this prefix on the LAN interface of the router they provided you, so your hosts receive this prefix via the router advertisement instead of the one the router currently advertise.   The other option is to have you own router and configure it to advertise your own prefix assigned by LACNIC.   Regards, ...

Could you please elaborate on your topology. For you servers to receive router advertisement from your service provider, your local LAN would need to be bridged to the WAN interface.   Regards, ... View more

Who is your Mobile Service Provider. I know T Mobile only assign IPv6 addresses on most of their user's phone and go through a NAT64 gateway when the destination host only have an IPv4 address.   You would also need to use NAT64 in your network to allow server with an IPv6 addresses to be accesible from IPv4 only clients.   Regards, ...

Hi,   There is no such concept in IOS or IOS-XR. By default, the best path is selected, whether MPLS is enabled on it or not. In a service provider network, all the links will either be all MPLS or all native IP and in the case of an MPLS network, all links will be MPLS and the case where a link does not have MPLS enabled is more likely a misconfiguration than the intended configuration.   To ensure that all links are MPLS enabled, you can configure a feature called LDP IGP Synchronization, which will cause the IGP to assign a very high metric to a link where LDP is not configured or not functioning properly.   You can also configure "mpls ldp autoconfig" to configure LDP automatically to all links included in the core IGP.   Regards,     ...

RFC5549 is not currently supported in IOS. Without RFC5549 support, the next hop needs to be the same as the configured address family. In your case you need to support both ipv4 and ipv6 through FlexVPN.   Regards, ... View more

According to the Cisco Feature Navigator, it requires a 2691 to run MPLS.   http://cfn.cloudapps.cisco.com/ITDIT/CFN/jsp/index.jsp   Regards, ... View more

The way to verify that, is to check which protocol is the source of the route in the RIB.   Regards, ... View more

> how the ISP will determine which prefix is being advertised by which ASN ?    They ISPs receive one prefix on the session with one ASN and the other two prefixes on the session with the other ASN. You just need to make sure that you only advertise the proper prefixe(s) on the respective session using your outbound route-map.   >neighbor 138. X .X. X  remote-as  11111 >neighbor   138. X .X. X  route-map LOCALONLY out >neighbor 180. X.X.X  remote-as  22222 >neighbor   180. X.X.X  route-map LOCALONLY out   Why do use a different remote-as f you only peer with one ISP?   Regards,   ...

I am not sure I understand your question. Your ISP will have 2 sessions with the 2 different ASNs. The 3 prefixes will be learnt by your ISP and routing will happen as usual. Does that answer your question? If not, can you clarify the question.   Regards, ... View more
