i need to disable the label aggregation on mpls-vpn setup. i need to se on the PE router that for each static route for vrf, or actual vrf config for port, another label is added in the "sh mpls forwarding table". how can i do this?
first, "show mpls forwarding-table" will only list local labels other than implicit-null label.
With every connected network in global routing, the default is to announce a "pop" i.e. a null label. The resason is, that the PE needs to strip of the label and investigate the destination IP to figure out, whether the packet is for itself or not.
Assume f.e. a PE with a directly connected LAN with a couple of hosts. A PE can only determine the proper host to send a packet to, if the destination IP is known.
If a network is connected to a VRF, basically the same applies as above. Yet there needs to be a VPN label to identify the VRF context. So in "show mpls forwarding-table" those VPN labels will show up as aggregate. This simply means, that the PE needs the VPN label to identify the VRF, but then also needs to look up the destination IP to figure out the proper host to send the packet to.
Thus "aggregate" labels are inevitably necessary.
Finally: what is your intention to have no "aggregate" in the output?
