Hi folks,

How do you think about BIER for= Native Multicast ?

(1) Use COMMON upstream-assigne= d VpnLabel defined in draft-ietf-bier-mvpn for GTM also, because GTM use th= e same arch as BGP-MVPN (See Native Instance as a COMMON VRF instance).

(2) Use special MPLS Label velu= e 0 and 2 as upstream-assigned VpnLabel, so the GTM and the case when BGP-M= VPN signal is not used both can use in a same manner.

(3) Use a BIER Proto=3D4/6 for = Native Multicast using GTM and Native Multicast not using GTM, while using = BIER Proto=3D2 for draft-ietf-bier-mvpn.

 

Thanks

Jingrong

Hi folks,

How do you think about BIER for Native Multicast ?

(1) Use COMMON upstream-assigned VpnLabel defined in= draft-ietf-bier-mvpn for GTM also, because GTM use the same arch as BGP-MV= PN (See Native Instance as a COMMON VRF instance).

(2) Use special MPLS Label velue 0 and 2 as upstream= -assigned VpnLabel, so the GTM and the case when BGP-MVPN signal is not use= d both can use in a same manner.

(3) Use a BIER Proto=3D4/6 for Native Multicast usin= g GTM and Native Multicast not using GTM, while using BIER Proto=3D2 for dr= aft-ietf-bier-mvpn.

 

Thanks

Jingrong

Dear all

 

Just a general comment on ISIS and R and X flag, the= re is some ambiguity on these flags when as an example

 

1.        &n= bsp;   Leaking BIER Sub-TLVs between Multi-instance ISIS, it woul= d make sense to not set the X flag when a local prefix is redistributed bet= ween instances.

 

[Les:] As per https://tools.ietf.org/html/rfc7794#section-2.1 <= /b>

 

“X-Flag:  External Prefix Flag (Bit 0)

      Set if the prefix has been redi= stributed from another protocol.

      This includes the case where mu= ltiple virtual routers are

      supported and the source of the= redistributed prefix is another

  &nbs= p;   IS-IS instance.”

 

2.        &n= bsp;   Same as SR In the case where a Level-1-2 router has local interface addresses configur= ed in one level, it may also propagate these addresses into the other level= .  In such case, the Level-1-2 router MUST NOT set the R bit. 

 

[Les= :] When an L1L2 router advertises its local addresses it may do so in its o= wn L1 and/or L2 LSPs. This is NOT “leaking” and the R-bit will = NOT be set in such cases.

Leak= ing is when an L1L2 router leaks prefixes originated by other routers upwar= ds or downwards.
