What RFC for MPLS is supported?

[ssieger]

Hi,

does anybody know what rfc's regarding mpls are supported by cisco (f.e. ASR9000 or Nexus 7000)?

TiA,

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,

Ivan.

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.

Ivan, Alex, thanks for your kind support. That is the information i need, i guess.
