Pushed due to ExternalGateway slip

Comment by Keith Burns [ 10/Jun/15 ]

A lot of progress made yesterday now I can focus on this.

Should publish first major patch today but essentially:

  • Added specific ChainActionFlow class for handling of chain specific flows.
  • Added simultaneous multiencap support (VXLAN, VXLANGPE)
  • Ensure non-symmetric chain, path. Not supported Li
  • Added setting of C1/C2 in ExternalTable per destination

This required a lot of pipeline work. The issue was that PolicyEnforcer is where we know about chains, but is still very "EPG/condition" centric, where a lot of the NSH header information is destination specific. Had to work on moving the final write of dest/source specific metadata, tunnelDests etc to the External pipeline which is all written from a new class ChainActionFlows.

Asymmetric chain: Client’s packet to HTTP server gets chained, return path is not.

So far tested:
multiGBP classifier
MultiSFF/SF
multiEncap (VXLAN for ALLOW, VXLAN-GPE for CHAIN).
All good, now working on
symmetric chain (got a plan)
coexistence i.e. GBP classifier + SFC SFF on same bridge/flowtable (got a plan).
