[c-nsp] ME3600 - SVI's + Service Instances

Hi Everyone,

Very new to the ME3600 platform, so hoping someone can assist with the following:

We currently have 4948's connecting to various carriers - Each port is a trunk, and has a vlan per tail.

int gig1/1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk allowed vlan 10,20,30

We then have another port on the 4948's (Trunk), that allows all vlans from all the carrier AGG ports that connects to 7200's or ASR1000's (We have multiple POP's), and each vlan is then added to dot1q subint and thrown into a vrf or standard "Inet" Interface....we also apply service-policys (egress shaping/ingress marking) on the L3 Interfaces

We are wanting to run MPLS on the ME3600s, and do all the L3 stuff on them rather than the 7200'sand ASR's - So, we will still have the 4948's, multiple carrier AGG's, multiple vlans's but the trunk port(From the 4948s) that currently goes to the 7200's and ASR's will now go to the ME3600s - So, a few questions:

1. What would the ME3600 Trunk port(That connects back to the 4948) config look like?  i.e. Similar to how we currently do it (switchport trunk allowed vlan 10,20.30,40...), and then create SVI's for each vlan and apply L3/VRF/service policies? Or do SVI's not support service policies and we would need to use service instances? (The 4948's typically have ~100+ vlans(tails) from the various carrriers)

2. If service instances are required, can anyone please provide an example of how the config would look (Or point me to some documentation please?)

Thanks in advance for your help.
