Hi Ivan,

thanks for the fast response, where can i find this kind of information? Is it the same for the Nexus 7k?

Greetings,

Stephan

Stephan, my pleasure!

For Nexus 7k please have a look at

http://www.cisco.com/en/US/docs/switches/datacenter/sw/5_x/nx-os/mpls/configuration/guide/mp_ldp_overview.html

in there, just navigate through all the features listed and have a look at RFC section where available. For ASR9k I just keep track of the RFC'es myself, so didn't check CCO for that.

HTH,

What RFC for MPLS is supported?

Hi Stephan

Here is the list of MPLS features available in NX-OS 5.2.1, many of them are described in several RFC - so listing all references is quite difficult. I'll put some key references below:

MPLS (RFC 3031)

    L3VPN (RFC 4364)

    LDP (RFC 3036)

MPLS-TE (RFC 2702)

    RSVP TE/FRR (RFC 3209)

    (FRR req. XL HW)

  MPLS-OAM

    LSP Ping & Traceroute

    TE Ping & Traceroute

    ECMP Tree Trace

MIBS - RFC 3813, RFC 3815, RFC 4382, RFC 3812

MPLS-QoS

MPLS-HA  (w/ ISSU)

MPLS-Security

MVPNv4

6VPE/6PE (RFC 4798)

Cheers,

Alex

Stephan,

to add more to Alex's point these are the features currently being supported since 5.2.1, in 6.2 we'll see more L2-related MPLS features like VPLS and EoMPLS. So, the list is not finished yet!

HTH,

Ivan.
