Thanks guys, it's working now :) I missed something very basic: no IP's
available in the global routing table to set the BGP Rid:
PE#sh ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static
route
o - ODR, P - periodic downloaded static route
Gateway of last resort is not set
PE#conf t
Enter configuration commands, one per line. End with CNTL/Z.
PE(config)#int lo0
PE(config-if)#
PE(config-if)#ip add 100.100.100.100 255.255.255.255
PE(config-if)#
PE(config-if)#
01:02:52: %LINK-3-UPDOWN: Interface Loopback0, changed state to up
01:02:53: %LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback0, changed
state to up
PE(config-if)#end
PE#
PE#sh ip bgp vpnv4 all
BGP table version is 13, local router ID is 100.100.100.100
Status codes: s suppressed, d damped, h history, * valid, > best, i -
internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete

Technically speaking, or any other interface in the main routing table.
Regarding your other comment:
> You can't have 2 VRFs under one EIGRP process, hence redistribution.
You can have them, but they will not "see" each other. It is very unusual in
this case to redistribute between them (so much so, that I'm not even sure
if it would be possible). The "best-practice" is what Anonio did here and
run dummy MP-BGP to leak between VRF's.
