Hi SWINOG members,
we’re a LIR, we got a /32 from RIPE and we want
to allocate /40s and /48s to customers. Only snag is that
the customers will not have their Internet feed from us but
from any Service Provider of their choice. The customers
will have to convince their SPs (X, Y, Z) to route these
„non X,Y,Z” or “foreign“ prefixes. We’re getting a lot of
“raised eyebrows” about this. What’s this about prefixes
longer that /32 not being propagated? When I look at the
IPv6 table I see:
IPv6 Routing Table Summary - 8625 entries
5 local, 2 connected, 3 static, 0 RIP, 8615
BGP 0 IS-IS, 0 OSPF
Number of prefixes:
/0: 1, /8: 1, /10: 1, /12: 1, /16: 1, /19:
2, /20: 5, /21: 3
/22: 5, /23: 5, /24: 7, /25: 4, /26: 9,
/27: 10, /28: 31, /29: 19
/30: 15, /31: 13, /32: 4049, /33: 97, /34:
87, /35: 93, /36: 242, /37: 7
/38: 50, /39: 22, /40: 385, /41: 12, /42:
18, /43: 34, /44: 151, /45: 15
/46: 75, /47: 45, /48: 3006, /49: 3, /50:
1, /52: 5, /56: 9, /64: 40
/126: 1, /128: 45
So where did all the /48s come from ... also
one or two /40s... ??
What do you think about this? If you’re a SP
would you route the /48s or /40s from the customers? What
about your upstream peers?
Thanks in advance for your answers.
