remarks: | for community support. |
remarks: | |
remarks: | 4. table 2 describes whether a beanfield upstream asn has support |
remarks: | for the equivalent traffic engineering community action that we |

remarks: | that upstream. |
remarks: | |
remarks: | example: 2914 supports the equivalent of 21949:9011. that is, |
remarks: | when a prefix tagged with 21949:9011 is announced to 2914, we |
remarks: | map to the 2914 equivalent of 21949:9011. |

remarks: | any match(es). |
remarks: | |

remarks: | received communities as defined in tables 4 and 5 denote the |
remarks: | prefix origin. |
