Hello all, I have a question regarding Netflow and MPLS that I hope someone can help. In search for clarification on this topic I ended up in some pages that I'll include the URL.
http://www.cisco.com/en/US/docs/ios/12_2t/12_2t15/feature/guide/ft_nfsub.html Based on this link, (besides the collector and version) to enable netflow under an interface we use "ip route-cache flow" and to enable under a subinterface we use "ip flow ingress". Now my confusion arises when I look at both these links: http://www.cisco.com/en/US/docs/ios/netflow/configuration/guide/cfg_mpls_netflow_ps6350_TSD_Products_Configuration_Guide_Chapter.html http://www.cisco.com/en/US/docs/ios/12_1t/12_1t5/feature/guide/egress.html In the upper one, to configure the MPLS aware netflow just the "ip flow ingress" is mentioned. In the second link however, "mpls netflow egress" is mentioned. Although I notice that the first command is ingress and the second is egress, what would be the say to use them if we got asked to configure mpls aware netflow on some interfaces? Should we look at the interface to see if the ingree/egress is labeled or not, deciding which one to apply based on that? What is your advice to approach this topic? Thanks in advance. Regards, Fernando.
