[c-nsp] EVCs/BDIs/SVIs

[Waris Sagheer (waris)]

SVI - Switched Virtual Interface is defined in IOS for configuring L3 interfaces. For example in ME3600X/ME3800X/ME3600X-24CX, SVI is being configured under EVC for configuring IP/L3VPN/MPLS interfaces.

BDI - It is same the thing as SVI but in IOS XE. IOS XE has the notion of BDI. For example ASR903, for configuring L3 Interfaces you need to configure BDI under EVC interface.

BVI - It is the same as SVI or BDI in IOS XR. BTW there used to be BVI in legacy IOS so please do not confuse with IOS BVI.

What is the different between a BDI on ASRs and an SVI?

Looking around the Internet they seem to be SVIs that you can bridge a
service instance to except they are called Bridge Domain Interface
instead of Switch Virtual Interface (I guess becaus these are routers
not switches?).

Any other difference apart from the name? Are they essentialy SVIs?


Cheers,
James.


Somethign I missed off of the back of that previous email - are BDIs
the same as more traditional BVIs (Bridge Virtual Interfaces) or do
they do extra functions?

James.
