Hi

OSPF generates routes with four source values:

RTS_OSPF, RTS_OSPF_IA, RTS_OSPF_EXT1 and RTS_OSPF_EXT2.

(for internal, inter-area, type 1 external and type 2 external routes).

So in your case you just export internal OSPF routes, not the E2 route.

Also note you can write the condition using sets:

if source ~ [ RTS_STATIC, RTS_BGP, RTS_OSPF, RTS_OSPF_IA, RTS_OSPF_EXT1, RTS_OSPF_EXT2 ] then ...

  show route export <channel>
  (for should be exported)

or

  show route exported <channel>
  (for was exported)
