Forwarding Protocols • Re: Status of ROS V7 for BGP, MPLS, VPLS

Upgraded a 6.9.13 production config on a test router today. Config was a vanilla implementation as per reference design in documentation, of OSPF / MPLS / LDP / BGP signalled VPLS in a P/PE role. No VRF4 implemented. MPLS MTU set to 2000

Upgraded using the WebUI Packages menu, CCR1009 hardware.

Upgrade path 6.9.13 -> 7.12.1 (upgrade) -> 7.14.1

Problems encountered:

• Update to 7.12.1 broke MPLS LDP Filters:
  
  Before:
  
  /mpls ldp advertise-filter> print
  Flags: X - disabled
  # PREFIX NEIGHBOR ADVERTISE
  0 10.1.255.0/24 all yes
  1 0.0.0.0/0 all no
  
  After:
  /mpls/ldp/advertise-filter> print detail
  Flags: X - disabled
  0 prefix=10.1.255.0/24 neighbor=0.0.0.0 advertise=yes
  
  1 prefix=0.0.0.0/0 neighbor=0.0.0.0 advertise=no
  
  This matched only peers with IP 0.0.0.0. ie. no match

• Update to 7.12.1 lost configuration for MPLS MTU
  
  Before:
  /mpls interface> print detail
  Flags: X - disabled, * - default
  0 * interface=all mpls-mtu=2000
  
  After:
  /mpls interface> print detail
  
  Flags: X - disabled; * - builtin

Otherwise process was reasonably smooth. Hopefully this saves someone a little time when upgrading.
