Hi there,
currently with me is ASR 1001-X. i would like to upgrade to 5Gbps. 2x10 GE port still yet to be used and tried to activate(unshut) this 10GE port, EULA pop out and it doesn't let me to activate the port because no license under this 10GE port.

My questions are:
1. is it need to activate license for 10GE port? may i know part# for this license if needed?
2. this router can support BGP routing?
3. If i want to add 1 more SFP slot, may i know part# for it?
And for the SFP transceiver module, can i select this: GLC-LH-SMD= (1000BASE-LX/LH SFP transceiver module, MMF/SMF, 1310nm, DOM) ?
For bandwidth performance license, i can choose from these 2 as below, correct me if i am wrong.
FLSA1-1X-2.5-10G : Upgrade from 2.5 Gbps to 10 Gbps License for ASR 1001-X
FLSA1-1X-2.5-20G : Upgrade from 2.5 Gbps to 20 Gbps License for ASR 1001-X
Thank you.
