Next-hop-self is enabled automatically under vpnvX AF. If the code supports it I'd recommend:
address-family vpnv4 bgp advertise-best-external <-- enables best-external + pic(if supported). no bgp recursion host <--disables recursive lookup for BGP NHs. bgp nexthop route-map BGP_NHT <--specifies which prefixes qualify as BGP NHs. bgp nexthop trigger delay 0 <--allows BGP to act on IGP events immediately(enable if FRR backup is available for the BGP NH). route-map BGP_NHT permit 10 match ip address prefix-list PE_LOOPBACKS match source-protocol "igp" <--if you are using hierarchical MPLS you need to add BGP there as well. route-map BGP_NHT permit 20 match source-protocol connected adam > -----Original Message----- > From: cisco-nsp [mailto:[email protected]] On Behalf Of > CiscoNSP List > Sent: Friday, September 19, 2014 3:32 AM > To: Will Tardy; [email protected] > Subject: Re: [c-nsp] next-hop-self under address-family vpnv4 also? > > Cheers. > > Any other "tweaks" to default config you recommend? i.e. timers etc? > > > > From: [email protected] > > To: [email protected] > > Date: Fri, 19 Sep 2014 00:42:23 +0000 > > Subject: Re: [c-nsp] next-hop-self under address-family vpnv4 also? > > > > It¹s not needed. > > > > > > "address-family vpnv4" section is used to define which routers > > participate in the VPNv4.
